Radical. Tubular. Bodacious. Gnarly. Basically anything a Teenage Mutant Ninja Turtle would have said.

I still use most of the hella tight slang I grew up with

Retard.

Information superhighway

Calling others gay or disabled as a slur.

Syke. Or psych. Early 90's kid slang, had a definition akin to just kidding or fooled you but more mean spirited. Said to mark the previous statement as intended purely to mess with the listener's mind or psych them out. Similar in spirit to ending a sarcastically spoken sentence with "NOT!" though distinct.

"Yeah man, you can drive my car. Psych! You're not touching my ride."

The more I type about it, the less "psych" looks like a valid English word.

it's a free country!

All that and a bag of chips

Grody.

I still call things grody, but it's apparently twee and shit to say now.

I didn't learn until an embarrassingly late age that you shouldn't say "jewed them down" or "I got gypped" when discussing prices, etc. Once it dawned on me what I was saying, I felt pretty mortified, but I grew up hearing them as normal words. It was just a thing you say.

Most of the stuff that was said back when I was in school were slurs. Like nearly every spoken sentence contained at least one slur.

'mad', as in 'very'

Fo sho, mostly because growing up made me realize I'm never really sho of anything no mo.

“Roflmao” :(

Also: cool beans

Back in the 70s we used to say "fuckin-A" as a kind of agreement

Bread. Yes, the word bread. It was quite popular in northern India. We use to call stupid people bread. Like, "Tu bread hai kya?" (Are you bread?)

This was alternative to the word "chutiya", which is a curse word, that we could use in front of teachers and elders.

rad. as in a conjunction of radical, which is also a slang term no longer in use.

people look at me real weird when tell them the cool thing they just told me is ‘rad’

Nobody says "cool' anymore. It feels weird when I say it unless I'm trying to be tubular or bodacious.

Or I'm hanging with my boys Fido Dido and Cool Spot drinking a nice glass of Sprite.

Phat

Mint

DL

Short for down low.

Never really hear it anymore.

Also

The bomb.

No one says that anymore.

And

Phat.

To refer to a thick gorgeous woman.

Dope

Beefed it / Biffed it

Don't hear "house" meaning to destroy something anymore.

Ima house you.
I'm about to house this burrito.

Phat and cattywhumpus.

Phat fell out of fashion and cattywhumpus isn't a thing where I live now

I once got made fun of at work for using "hella" about something. People are stupid.

bae is the one that was really everywhere and then just fell off a cliff.
