In your time, what was slang?

DRATS!

"That's the bomb"
"That's dope"
"You're a pigeon"

I grew up with shit like this:
 
Dude... like, that's freakin'retarded. No, actually, that's hellaretarded!
 
Sup? Really? sweet!
 
my bad. No, I mean it. Totally. Psyche!
 
No way! Yes Way!
 
Fine then, be like that.
 
Uuuuuuuuuuuhhhhhhhhhhhhhh.

Various ways to say testicles: Balls, Nards, Chode, Scrote.
 
I'm sooooooo 90's. 

Oh and for clarification, I'm from SoCal, where it's totally gnarly and radical all the time, man, for real.

I remember having to explain to some french kid what "Boner" meant  when I was 9 years old.
For the life of me, I couldn't figure out how to explain it. I mean, EVERYONE knows what a boner is right?
 
"It's when your dick gets hard... umm... ok? No?"
 
Awkward.

Yo and aight. I still use radical and awesome because I am lame like that. Mostly in a joking term though.

It was either tight, or boss. I still here people use legit as a word for cool and it bugs me,

Are you Down? --Are you ready to do something,you cool with something
Sapo --A lucky shot in basketball , usually all net shot  
Muff---People would call you this if you were acting stupid, and then procede to smack you on the back of the head. 
Dee Dee Dee-Stupid carlos mencia thing that people would say if something stupid happened. 

We got a few weird ones up here in Canadian land although these are probably just exclusive to my district.
 
Peel- To leave
Cheek it- Butt Sex
Dart- Cigarette 
Muck or Mucking- To eat
Calling something "Chrome"- Means Cool

" Nothing, i was a gen X kid so every thing we did was awesome and timeless. "

In my time, we considered "Protestant" to be slang. You know, like "That bonnet is so Protestant!"
