daboomchi

A word used by the underground culture of children ages 14-16 that is equivalent to the word owned, pwnd, or o(p)wnage. It is used whenever an individual "owns", tells off, or basically proves their superiority to another or many others. An exclamation point is usually added at the end of the word to emphasize the emotion represented when you use this word and show others how you just owned them. A "yeah, uh" can also be added for emphasis. The boom in daboomchi is accentuated for a better effect. So, in theory, you would say it like this, "Yeah UH daBOOMMMchi!!" This word/slang term was brought forth by dagrlz, especially Number 1 and 4
