When you get an instant
boner at the sight of something utterly sexual in nature but that
boner is quickly rescinded by something purely udesirebale
right next to it. It is one hell of a Juxtaposition. Its a spin on the popular phrase "Swing and a miss"
Guy 1:
Dude, Look at Carmen over there. She looks super
hot in that black sequin dress *gets a
boner*
Guy 2: Damn Straight, Bro.
Guy 1: Oh shit, she also brought her ugly friend Susan. *boner rescinded*
Guy 2: That's too bad. Well I guess its a Schwing and a miss.
