sneak bang 

Whilst in the midst of humping, the lover on top quickly removes themselves. Before the other lover realizes a third party quickly joins. This transition must be seemless, so the recipient does not become conscious of the sneak bang

Dude, my homie hasn't gotten ass in so long, so last night I had him come in and sneak bang my girlfriend. It was lit.

Sneak a bang 

When you have to sneak somewhere to have sex with someone to avoid being caught...

My friend and his girlfriend both still live at home with their parents and so they have to pull the sneak a bang whenever they wanna get frisky so they dont get caught by their parents.

Sneaky Banger 

When an artist who typically doesn't put out good music puts out a song that everyone seems to like. Tends to be used when the artist is disliked as well.

Tim: Did you hear the new Justin Bieber song?
Mark: Yeah, it was surprisingly good

Tim: Total sneaky banger
