Ball Sack Sleestak
The Sleestak type of sounds that are heard from the sucking, hissing, and slurping sounds someone makes when tea bagging or sucking on your ball sack while giving head.
Damn, That girl was a regular Ball Sack Sleestak when she went to town on my shaved sack the other night. I had to look down to make sure it was still her and not some "Land Of The Lost" character!
