A prostitute with a colostomy bag he can remove to give male customers some sidepocket.
That bum over there just got a colostomy bag and is trying to sell his sidepocket for crack!

A gay man who likes to BOTH fuck and to get fucked; one who is not exclusively a TOP or a BOTTOM but is a SIDEPOCKET. More chill than versatile.
NSA 25 yr. old sidepocket here looking for top or bottom NOW. Can give or get as long as someone get fucked and we both get off.
