Rigby is one of the two main characters in Regular Show, the Cartoon Network animated series that ran from 2010 to 2017, known for its slacker humour and sudden bursts of chaos. Short clips of Rigby shouting, panicking and overreacting have long circulated as reaction sounds because his voice is instantly recognisable and easy to drop into a joke. This intense ah works in the same way, giving creators a ready-made moment of cartoon panic that needs no context to land, which is why it keeps appearing in memes, edits and gaming videos.
