Definition
Off the charts; through the roof (beyond expectations).
Origins
From episode 28 of the anime TV series Dragon Ball Z ("The Return of Goku", 1997), referring to Goku's increase in power level. It should be noted that this phrase is a mistranslation from the first English dub produced by Funimation Productions and Saban Entertainment, whereas the line in the original Japanese script was 「8000以上だ！」 (lit. "Over eight thousand!"). Popularized by a 2006 YouTube Poop uploaded by user Kajetokun.
In Context
- "Nappa (Michael Dobson): Vegeta! What does the scouter say about his power level? / Vegeta (Brian Drummond): It's over nine thousand!"
