This Spanish slang term is used to refer to the person who ruins everything, the one who spoils the fun or the situation. It's derived from the word 'cheche' which is used to describe a spoil-sport or a killjoy, and 'pelicula' which means movie.
Examples
- Spanish: No invites a Juan a la fiesta, siempre es el che-che de la pelicula.
- English: Don't invite Juan to the party, he's always the one who ruins everything.
