A male homosexual who has yet to come out of the closet (or trunk).
A Scottish slang term for a male homosexual.
For example,

1. Did you see Dave looking at that bloke, I think he is a bit of a trunk monkey.
2. I feel sorry for Dave that he hasn't come to terms with his sexuality yet. He still tries to make his friends think he likes girls, but we all know he's a trunk monkey!
