Originally a popular video parody on YouTube and 4chan using characters from the nineties Japanese cartoon; DragonBall Z. The video took 15 seconds of episode footage, and dragged it over a minute and fifty seconds, producing a very repetitive effect. It is now used as an adjective synonymous with "cool" "great" "too hard" or to express the extreme circumstances in a situation.
"I started taking piano lessons, at first I sucked, but now I'm OVER NINE THOUSAND."
"No matter what I try, I just can't kill this stupid boss! IT'S OVER NINE THOUSAND! I give up!"
Its what Vegeta's scouter says about Kakorat's power level.
Nappa: Vegeta, whats the scouter say about his power level?
Vegeta: It's over NINE THOUSAND (THOUSAAAAAAAAAAAAAAAAND)
