The phrase is Italian dialect for I am not drunk, addressed to someone called Lello, and that direct, personal address is part of why the clip travels so well as a reaction. Its exact source is not documented in the listing, so it circulates mainly as a standalone soundboard and short-video audio rather than as a quote tied to a confirmed scene. Online, users lift just the denial and place it over unrelated footage, letting the confident protest explain the whole situation without any extra setup or explanation needed.
