|1.||Men's room CB|
A CB radio in the men's rest room. Something that doesn't exist in reallity but some men try to get women to believe in it just for fun.
John: sorry I was in there so long. I was talking on the men's room CB.
Kathy: There is no CB in the men's room.
Joyn: How do you know? Have you ever been in the men's room?
