The clip comes from the Victor bumper used by Just For Laughs Gags, the hidden camera prank series built around silent street gags and audience reactions. Victor's closing cry of Mommy, it's over became a familiar sign off because it appeared at the end of the show's videos, marking the point where the prank stopped and the segment wrapped up. Shared online as a standalone sound, it kept that ending function and is now reused in edits whenever creators need a loud, funny way to declare something finished.
