Top definition
A thin black penis completely surrounded by a frizzly mane of pubic hair. The penis is usually unfindable except be its' owner, who frequently keeps it tucked near his nut sack so he can find it easily. Although the African Tunnel Monkey is not a measure of dick size, it is uncommon to find a normal sized lingum engulfed in pubic hair.
Last night I was looking to get my twat stuffed by this new guy, but when he pulled down his pants all I could see was this African Tunnel Monkey... so I friend-zoned him.
