“Get lost, Chumley” comes from Hitman: Blood Money, the 2006 stealth video game developed by IO Interactive. Players extracted and shared memorable dialogue from the game as short audio clips, allowing lines outside the main story to circulate through soundboards, gaming videos, and reaction edits. This one remains useful because its curt delivery works without needing gameplay context. The unusual name Chumley also gives the dismissal a distinctive, humorous quality that separates it from more ordinary rejection phrases.
