trapperkeeper

Used to describe one who commonly ends a night of partying early. Derived from the phrase "to fold" as in folding a poker hand, so one could be called a folder. An old popular name brand of folder used in school was the Trapper Keeper.

The party is still going, why is he'she leaving already?

Ah, he's/she's a trapperkeeper
