It’s over 9000 refers to a memorable catchphrase, originating from a clumsy translation of the original Japanese text of Dragon Ball Z.
Both online and in the series, the phrase is used to refer to the overcharged and powerful nature of a person or a utensil.
The quote originates from Season 1 Episode 21 of Dragon Ball Z, which first aired on April 19th, 1997, under the title The Return of Goku.
During the episode, Goku learns about the death of his friend, Piccolo during his battle against Vegeta, sending him into a rage.
His opponents then measure his Power Levels and realize “It’s over 9000”.
The original Japanese text, however, said “It’s over 8000”.
This difference exists only in the English, Croatian and Hindi translations.
An early instance of the line along with the clip was uploaded to the /b/ board of 4chan by user Kajetokun in 2006.
Following this, the expression would gain more popularity on YTMND and 4chan’s boards, as well as appearing on YouTube.
The first isolated clip of the scene was uploaded to YouTube by user chowderrockz on June 24th, 2008.
Over the years, “It’s over 9000” would be referenced in memes on sites like 9GAG, me.me, iFunny, Reddit as well as videos on YouTube and songs all over the web.
