look up any word, like donkey punch:
 
1.
A man who likes to play on a pink oboe. He may also smoke pink cigars. More simply put, he is gay. The phrase 'ringbang' derives from the act of anal intercourse, describing the base of the penis reaching the rectal opening, causing a Rhythmic banging noise.

Commonly used as an insult, at least by me. I think it's funny.
Just get on with your work, you fucking ringbang.
