WTF BOOM! is a sound/video clip that was used like hell in selected YouTube Poops. The clip is from the Steven Moustache Show with a character shouting "WHAT THE FU-'" but that phrase is interrupted with a nuclear explosion, An unknown person saying "BOOOOOOOOOM!!!!!!" and a skeleton pilot laughs.
- It was once used in nearly all of Thechairman45's videos. After he started uploading better ones, he took down all of the old ones when he realized how crappy they were.
