Bat Wing 

When a male pulls down the front of their drawers, and they have an overly hairy package (Don King style) and exposes others to the horrible sight. Almost like a frontal mooning.

The chick checked out my bat wing, and was disgusted, and asked me to trim it up before going down on me.

Tim's bat wing is out of control.
