Earliest usage I've found (on the web): "strange or funny-haha?" --title of CD by the Japanese electronic artist "bisk" (a/k/a Fujikawa Naohiro). Sub Rosa 118, earliest date given: June 1997; b) emphasizes funniness by repetition; c) performs funniness by using a silly phrase.

An absolute terror of a comeback that destroys any argument with nuclear explosions, both hypothetical and real. The power level of this phrase trumps even that of the ancient "no u", for the opponent's opinion is left in limbo and their existence is made a lie. Use only in emergencies or when attempting to end a "no u" war.
Jeff: ur mom gay
Mike: no u
Jeff: no u
Mike: haha ur face
*Jeff explodes in an instant and is sent to hell, where Satan himself summons him and utters the phrase "ur family tree LGBT", causing Jeff's pain to multiply exponentially as he is spun in a circle as a bunch of gay people slap his ass and continue to pelt "ur mom gay" at him

From what i have gathered, this is a way most people get by saying insulting and asshole-like things.

Examples:
Asshole: dude your fat, retarded, ugly and gay! HAHA j/k!!

Me: you fuckin dick.

Asshole: what? i said j/k!!
