When a male squats down with shorts and the ball sack makes a buldging underneath him.
Can also mean the act of tea bagging one woman and than placing your sacred ones into another womans mouth.
Guy 1: dude wtf?
Guy 2: what?
Guy 1: quit squating down to grab that shit, your swab bag is showing.
Yeah bro it was pretty sweet. Those two lovely ladies that I fertilized were such freaks. They let me swab bag them after I came.
