favorite out of date slang term?

This isn't "nobody uses them", because undoubtedly there is some asshole who thinks it's 'funny' to say out of sight or groovy, it's more of "nobody uses them ENOUGH in regular conversation".

Like Radical. Not enough people say radical anymore. Or use the cool radical hand signal (pinky/thumb out and waggle your hand, of course)

WHAT SAY YOU, GIANT BOMB COMMUNITY?

bling

neato, tubular, cowabunga

slambert

As you said, radical or rad.

'The bee's knees" is a common favorite of mine.

bitchin'

All the Bill & Ted/Ninja Turtle/Surfer dude ones.

"Groovy."

"Hella."

Wind your neck in big lad!

This is the only true answer as far as I'm concerned.

"Swell."

Rad and groovy.

"boss"

I use rad pretty regularly.

I... Had no idea it was out of date.

"boss"

how did I not think of this

Everything's jake.

@Animasta: it's sad, but I use it all the time.

I'm partial to the sporadic use of 'dope'.

Mamaluke,Shellacking and Doggonit !

I still use rad.

I occasionally use the word "Grouse" which is super out of date aussie slang......one might even call it "daggy".

mook

Gettin' jiggy with it.

Dude

The way Wayne says "Excellent."

saying something is pimp.

It started off as a joke, but I now say "Ace" all the time instead of "good" or "OK".

Calling something bad a "drag."

Confirming with "right on."

BOOYAH!

I still say bummer like some kind of Ninja Turtle. Most people I know use "word" a lot too and that's been around forever.

"fly"

Boss, rad, and bee's knees are ones I like.

Streets ahead.

Brosef and/or Broski

Bonus!

Can you dig it.

I knew there was a reason I liked you. I say rad or radical all the time.

Yeah I'm a pretty big fan of "most triumphant".

Also...

SSSSSSSSSSSSSSMOKIN'!

"Swell."

"Swell? You know, Clark BeachThunder, there are very few people left in the world these days who sound comfortable saying that word."

I'll go with: "Marvy. Fab. Far out."

Fresh, Funk Fresh, Dope (I think this made a hipster comeback though), Def, Tight, ill, illin'. I still use the first three.

Wait. What have you got against "groovy" now?

If it's good enough for Bruce...

...it's good enough for anyone!

No dice.

Boss.

That's what I was going to say. I use it all the time.

wowsers is one I hate and my other halfs friend always says 'excellent' in a Bill and Ted style..it proper winds me up

I use 'brilliant' a lot, but maybe that's still a thing, although I've had some American girls lose their minds when I've said it, so...
