Thwomp is a heavy stone enemy from the Super Mario games, famous for hovering above a path and slamming down on players who pass underneath. The uuhhuhuh clip is linked in its file data to a fan compilation called 20 Thwomp Sound Variations in 30 Seconds by Vitoamiibo, which presents different takes on the character's sound. As a standalone clip it has circulated mainly as a compact Mario-themed reaction sound, valued less for its game accuracy than for its short, human-sounding timing in edits and soundboards.
