A shack in which a man goes to in order to ejaculate in peace.

It is essentially the countious process of MULTIPLE male participants ejeculating or so-called "cumming" into the same female (most commonly the vagina, mouth, or anus). The name comes from the reference to a shack as an often dirty dwelling which can be virtually used by almost anyone (hence the implication of a whore).

the absolute best pick-up line you can use when you see a TOTALLY THICC KWEEN WITH A BIG BOOTAY (male or female)
