Avant-tarde 

Hipsters who think they are cool, new and fresh, and have missed the irony in their retardedness.

The leading edge of edgy hipsters who have their heads so far up their arseholes with not an ounce of cool or self-awareness to allow them to realise that they are not in any way shape or form presenting anything new in their style, action, diction or modus operandi.

1) That guy, Don Atari, is so avant-garde. (adjective)

2) My sister is one of the avant-tarde. (noun)

Avant Tard 

It's for all those times when the art snobbery of a piece reaches such high levels that the feeble attempts made at being "exotic" or "ground breaking" just lands the artist squarely in the realm of retardation.

"I went to this new art gallery last week but it was so Avant Tard that it hurt!"

Avant-tard 

The attempt to pull off something as edgy, experimental and cool but fails.

"Wow. The band was totally avant-tard."

Avant Tard 

Cutting edge retard. Similar to avant guard, meaning cutting edge or ahead of its time, yet retarded.

Corky's performance in episode #12 of 'Life Goes On' was sooooo Avant Tard!

Post Avantgarde Jazzcore 

A fake genre of music used as a retort to people who claim to listen to a bunch of made up genres of music in order to seem interesting.

Rumor has it, only one band ever existed. They played only one show to an empty room, recorded and mixed the show into a live album, produced one copy, and then never spoke or saw each other again. The album was recorded through an old walkman, and can only be played through player piano scrolls.

Man 1: I listen to very obscure music, shoegaze-acidhouse, downtempo-core, Post-doublecore, chamberfolk...
Man 2: Yes, I too only listen to post avantgarde jazzcore, but these plebeians will never understand it. Surely YOU, have heard of it...?
