Put this clip at the moment the chase joke starts, before any reaction lands. Follow it with the Running Sound Effect Button to sell the escape, then add the Oh Shit Echo Sound Button as the panicked reply from the group.

This is a 5-second spoken clip built around a character called Yaycub, presented as a child predator who is coming to get you. A voice delivers that warning as the whole joke. It feels creepy and unsettling on purpose, with the threat played for dark, absurd humour rather than real menace, which is why people use it as a shock reaction.
