The sound your ballsack makes when pounding a tight slizz from behind; a good sack flap goes to a beat and makes a soft thumping noise... & can lead to minor bruising and irritation of the stomach region of the partner whos tight slizz or smelly balloon knot is being ravaged
Kelly: "Whats that on your stomach?"
Sara: "I had a good Sack flapping last night"
Kelly: "Oh i got sack flapped last wednesday; and his beanbag bruised the hell out of my tummy "

When a man is experiencing liquiballs and the skin of his scrotum adheres to the side of his leg and/or taint with a superglue like bond. This effects causes said man extreme discomfort making it impossible for him to sit still without awkwardly and obviously adjusting his junk. Shaving the scrotum dramatically increases the stickiness of sticky sack.
Bobby unintentionally forfeited the job opportunity when the attractive female HR representative caught him adjusting his wicked case of sticky sack.
