Let's come up with some ME2 Haikus. Anything's alright as long as it is ME2 related and has 5, 7, 5 syllables. I'll start:
 
Oh no, my fish died

Feed my fish red head
Went to my cabin found them dead
Tali I choose you instead
 
I throw you a singularity
Makes you part of my polarity
I'm questioning Mordin's sexuality
 
Shepard. That's all for now
Shepard. Shepard
That's all for now.
 
(Based on actual game events, asked Kelly to feed my fish, went to cabin right after asking and they were dead!)

Shepard, Wrex,
Shepard, Wrex,
Shepard, Wrex
*raging Wrex* "What the fuck do you want!? God..."

I need an arid spot, 
My skin is scaly lizard. 
Thinking, my thoughts speak. 
  
GUESS WHO I AM?! 
 
Circuits and panels, 
my self is inorganic. 
Shepard - Commander. 
 
I LOVE THAT ONE

We'll talk more later 
I should go, That's all for now 
I will let you work

Whew, it's dead at last.
ASSUMING DIRECT CONTROL!
Oh shit, not again!

Stupid swarm did bad.
Grabbing Garrus, so not right
Jack was tastier!
 
Wah wah wah wah wah!
Bitch whinge gripe fart moan sulk piss!
Piehole shut, Ashley.

It's 5 syllables, 7, then 5 again, no? 
 
Flyin' the Normandy 
Shot Down By The Collectors 
Now Shepard is Dead =(  
 
Pronounce flyin' like "fline" one syllable, bitches. 
 
Brought back from the dead 
Waking up in a weird bed 
Shot mechs in the head. 
 
(anyone wanna continue summing up the game in order, go right ahead)

Come on people.  Didn't we learn how to count syllables in like, kindergarten?
 
Rank has no meaning.
The right hand of the council,
I am a Spectre.

OMG! 50 Cent?
No, my Shepard looks like him
Jumping big-ass ramps.
 
I am a Haiku
About the game Mass Effect 2
You should be afraid

" @XII_Sniper: Yes it is but then you break it with your first line  Fly-ing-the-nor-man-dy is 6, duder "

an alien, sexy.
if aiden is still dead
warm soup dries slowly.

" Whew, it's dead at last.
ASSUMING DIRECT CONTROL! 
Oh shit, not again! "

Shepard - 's all for now.
Shepard - that is all for now.
Shepard - 's all for now.

Shit, shit, shit, shit, shit

Shit, shit, shit, shit, shit, shit, shit
Shit, shit, what the shit! 

This thread would make good DLC. It'd be called "Haiku Mode," and all the main events would be fully voiced haiku.

It occured to me 
Jacob looks like Kanye West 
Don't interrupt me.

Ok, some more: 
 
Kaidan or Ashley:
"I HATE YOU, YOU'RE CERBERUS!!!"
That's the thanks I get?

Doctor, please help me!
"No! Go away, I'm busy -
I'm drinnnking braaaandeey"
 
Mechs everywhere,
Bam! Mechs scrapped; All crates in tact,
Nuke gun is magic!  
 
What I'd like to hear:
"optimistic proposal:
Let me join your squad"

Meeting with council,
"there's no such thing as reapers!"
Why'd I save those jerks? 
    
@ViciousAnchovy: That would be simultaneously awful and awesome.

M two ninety cain
 
Is a bucket full of pain
 
wins the fucking game

Criminal Hunter.
He is as cool as Batman. 
His name is Garrus.

For Mass Effect 3 
Although they aren't real fighters 
We need a volus. 
 
Garrus, do not ask
About the elevator
Tali's got a gun.

" Garrus, do not ask  

 About the elevator  

 Tali's got a gun. "

The new Citadel
Anderson, Udina's bitch
Race riots, my ass.
 
The Illusive Man,
Eyes like snowflakes and buttons,
What a jerk he is.
 
Kite the fucking husks
Kite the damn praetorian
I like real kites more
 
The Volus on drugs
So sure of his biotics
Funny cutscene, charge!
 
Probing for upgrades,
Uranus is depleted.
Hahaha, that's gross.

Anyone notice that
Zaeed kinda looks like a
melted Kurt Douglas?

If you're ever called 
A "borshtat"(?) by Tali, then 
You done fucked up bad.
