Jack Shack

When your wife/girlfriend is menstruating (i.e. on the rag) and the only sexual release available to you is masturbation.

(This is a tribute to the late comedian Robert Schimmel, who coined this phrase before his death in a song of the same name.)

John: "Hey. You alright, man? you look tense."

Ray: "Yeah. The wife is on the rag, man.. Gonna be a long week in the Jack Shack."

John: "Ah. Gotcha."
