Muscle Man, voiced by Sam Marin, is a main character in Cartoon Network's Regular Show, which ran from 2010 to 2017. His running 'my mom' jokes became one of the show's most quoted gags, built around a deliberate twist on classic your mom jokes. Clips of the line spread through YouTube edits, Vine-era reposts and soundboards in the 2010s, and the short shout survived as a standalone reaction sound long after the series ended, reused whenever a joke needs an unexpected self-directed punchline.
About this sound
Muscle Man shouting My mom from Regular Show, the classic insult comeback sound effect used for reaction videos, edits and joke punchlines online.
This is Muscle Man's signature one-liner from Regular Show, delivered in his loud, strained voice as a sudden 'My mom' punchline. He drops it after setting up a joke that sounds like it is about someone else, then flips it onto himself for an absurd twist. The short, shouted delivery makes it instantly recognisable even without the picture. It lands as a goofy, self-owning insult that feels more silly than mean, which is why the clip works as a quick reaction sting in edits and memes.
