I saw Jim in the pub again last night so I ran out of the back door went to the pub across the road. After ordering a pint I turned around and the cock was there smiling at me. Was a total boomerwang.
A man you used to sleep with who attempts to sleep with you again long after therelationship has ended. A boomerang wang. Can be used as a noun or a verb.
"Girl, did I tell you Matt messaged me last night? I threw that trash out last year! He's tryna boomerwang me."
