Yesterday I was playing with some friends at Isla as the defenders. At the second base we were doing so well where we got the attackers to 17 tickets. Everyone was near an almost destroyed crate B with no enemies or vehicles nearby. For a split second I saw three C4 markers near the crate surrounded by the team; I knew it wasn't the enemy's. When I turned away from it it exploded. 2 minutes later we lost the game but we could have won if the asshole (probably a booster but who knows) wasn't there.
 
I checked the scoreboard and our team had new people so it might have been one of them.
 
Any moments like that?

It's obviously a chopper whore (or a team of 'em). They pop on Valdez mostly. Killing friendly crates to get their 2min of fame in the Apache. Guess he wanted to sit in the Mi-24 Hind very very badly.
 
Most assholish behavior is somehow linked to chopper whoring. I bet 'Atacama Desert Conquest' is the map with the most teamkills on hardcore. 
 
Recently, I'm playing Assault kit with C4 (6 sticks & extra damage) as an attacker. Rushing in ninja style, as long as the cover hasn't been decimated yet. Trying to take out more than 50% of the M-COMs health before anybody knows I'm even there (now that's fucking with the enemies morale). I hate squadmates spawning in on my position and starting a ruckus getting me killed.

yup, seen that stupid shit before on a couple different occasions. Although, maybe some of them don't know it hurts the crate and they think they're setting a trap? I HAVE seen some tards do it on purpose though to move our defense back...
couple things that piss me off:
-other snipers crouching in on your sniping spot. Way to go moron, you're going to give me away because you're firing like crazy and not hitting anything.
-repairing your tank and someone jumps in. Not so much anymore though because when I repair, I stare at the map.
-and my favourite: the retard that jumps out of the low health tank in enemy territory, giving the enemies your only tank and making defense/offense MUCH harder.

When I go 36-10 in a game and still lose, and when I look at the scoreboard there were other people on my team like 0-13 and 1-17 and stuff. Not necessarily because they were bad, they were just afk the whole game or camping waaaaay too far back. 

One day I felt like being an asshole so I camped behind the enemy base and kept killing this one guy over and over again....After the match he sent me a message saying "Ur Asshole"....great grammar.

I've had teammates blowing up our own M-COMS before seriously...WTF.

I actually did that asshole thing of blowing up our own Mcoms and not just one but 6!
It was on Port Valdez an getting pretty late in the night going towards morning.
People were leaving the server and not enough new ones were coming in. Eventually the teams started getting very small.
Problem was my team was owning hard and by the time we got to Port Valdez and were defending the disbalance was 3:1  something like 12 to 4 we were basically up on the attackers hill killing them not allowing to exit. So even more people started to leave. The attackers basically had NO chance at all. It being late I decided to have some fun. So I switched class to assault with C4 and started to sabotage our own Mcoms so that the attackers could advance. This lasted untill the second to last base. By that time the defenders had about 6 people left and attackers 4. Some teammate started gettign pissed in chat that I was sabotaging our own Mcoms :)  So I switched to attack and the teams evened out 5 to 5. We proceeded to win the game. And at the start it was 4 to 12 with attackers getting spawn trapped and down to under 10 tickets before the first base :P

Every time I snipe I feel like an asshole.

" I've had teammates blowing up our own M-COMS before seriously...WTF. "

All the campers.
 
Goddamn....motherfucking....campers

Once, in the beta, I accidently used C4 on our own M-COM. Felt like an idiot.

hmm...some of the things I did was I destroyed the cover of my teammates who are hiding inside buildings and shooting through the windows.  And one was my teammate was using the stationary MG to shoot down the chopper in Isla Inocentes, then just for the heck of it, I shot the wall with a 40mm grenade, so he lost the MG.  It was funny back then, but now that I think about it, I feel ashamed for actually doing that...

People sniping. I don't have a problem with Recon players, due to the class being awesome, I have a problem with snipershowever.

I run into griefers all the time in hardcore mode. But friendly fire will do that for any game. 
 
Speaking of greifers, where has mano521 been anyway? I haven't heard one single grief story from that dude regarding this game.
 
In the PC version I especially hate chatty whiners who have something shitty to say about EVERYTHING that happens. Then when you call them on their shit, they begin directly griefing you. Makes me wish the PC version had a report user function like the 360 version has via Live.

"Once i had a dude on my team that was a real ass and was just teamkilling so i shot him in the head with the tracer gun. I think he was only seeing a blinking red light until he was killed. "

Last night I got a team kill destruction 2.0 on nelsons bay. I didnt mean to. I meant to place a single charge on the outside of the house, and wait until the M-com was destroyed (charge was set), but as soon as I rounded the corner an enemy was right there. I blew off my charge and got two enemy C4 kills, the M-com, but the house must have had too much damage because it collapsed with a friendly inside. Opps.

I just drove over a team mate engineer who was repairing my tank.
(about half an hour ago)
Simultaneously makes me want to blush and laugh my ass off.
I apologized :)

• When you happen upon a empty vehicle and you start repairing it, some fool jumps in it and takes off.
• Idiots who stat pad, they also TK aswell.
• People who blow up the building where the M-COM station is at. (I don't play on Rush anymore)
• People who whine about Snipers.
• People who go into your un-capable spawn and spawn camp/destroy vehicles.

Anything to do with a helicopter is an asshole moment. like morons we are losing why are half the team fighting over who gets to fly the helicopter!?! go capture a effing flag!

People on my friends list joining the other team just to get that silly 'Knife 5 of your friends' achievement and not resting until they have got their knife frag...
 
...basically an asshole moment because some of them aren't that good at the game and so instead of having fun and playing as a part of your squad, they spend the entire afternoon trying to stab you in the back for the sake of a silly achievement...sake

I like to load up my ATVs/jeeps with a pile of C4 and drive it into enemy tanks/groups.  It's surprisingly effective if they don't see you coming.

Some jerk teammate rigged C4 onto a quad as I was jumping onto it. Didn't see it until I got on, figured he'd be nice and not blow it up. Few seconds after getting on it, he blew it up and I died only to have it register as a suicide. Which sucks. Because I hate seing "Epic Fail" on the screen.
