I don't think its so much an argument between beer+pretzels crowd v. angst bunnies of the Sahara, as a very rare occurence that most have little experience with.

My, my... Aren't we the little angst bunny today? ¶ What happened? Choked on your daddie's ManToolTM again, and received the regular thrashing?

In the mid-80's we called them "angst bunnies"; then I started hearing "DIB's" (dress in black) and "goth".

ROTFL!!!!! Wiping tears of laughter! Excellent, excellent job. I don't think there are many angst cliches that were missed here, and as an angst bunny, I usually catch them all.

:::reaching for hankies::: ¶ The angst bunny counts this as a sumptous little bit of clover. Doing very, very well.

Yes, the angst bunny tap-danced all over the place with this one. […] ¶ […] thank you for deviating from your virtual series long enough to indulge the angst bunny, and give that bun a carrot.

Summary: Anya contemplates Xander, romance and this whole humanity Thing. And uncharacteristically sappy piece … my angst bunny's on holidays.

My god, woman, no wonder cyn65 is such an angst bunny when she thinks of you!

"Actually, what I liked about 'Titanic' wasn't so much the romance (though I liked that, too) but the detail they put into developing even the background characters, and how they managed to portray the event as a tragedy, not just a big special effect or a bang-wow disaster. Then again, I'm a confirmed angst-bunny.

In a fanfic, if used correctly, rape can be, and is, a very effective tool if a story is supposed to be really angsty -- and I'm a bit of an angst-bunny. I like angst, as long as the hurt/comfort equation gets its share of comfort too.

I missed this when it aired over here due to the fact that I don't have a tv, but I'm reliably informed the wife is a total angst-bunny because she's a vegetarian and the average Victorian diet didn't cater for that.

They do, yes, take the piss out of youthful angst-bunnies very effectively.
2001 August 28, David Damerell, "Re: New Releases - 20th August", uk.games.roleplay, Usenet,
Several of their games - especially Vampire, but all of the WoD games - were very successfully marketed as being more serious role playing. For Real Role Players. Not like those dungeon crawling games. No, no. Investigate the very crannies of the human condition. And stuff. ¶ […] ¶ Only a raging angst-bunny teenager would have believed that nonsense.

Most of my characters have some sort of impairment, often a crippling one, related to their signature power. Call me an angstbunny if you will, but it comes with the territory (...that of playing Malks and wraiths - great fun but not for everybody, I suppose).
