Sloppy poppin'

Sexual term used to describe an orifice creating a popping noise on an overly lubricated (preferably by natural means) phallus.

My friend's mother had my toe knuckles cracking from an amazing sloppy poppin' that was so wet, I had to put my socks in the dryer afterwards. When she pulled her mouth off of my junk, it was sloppy wet and there was a popping noise.
