tunnel slut

A whore that works the homeless in underpasses and subway tunnels. Made famous by the band INSEX.

tunnel butt slut

A person who has participated in anal sex so many times that their anus no longer closes back up afterwards, and therefore resembles a tunnel.

I don't know if I want to have anal sex anymore because I'm afraid of becoming a tunnel butt slut.
