have a girl you have no respect for go down on you on her knees while you're seated. if she's like most girls, she won't want you to 'icky' in her mouth, so warn her when you're about to. and as soon as she pulls off, clamp her head between your knees, bust on her forehead, pull out a dollar bill and slap it onto the newfound adhesive. then proceed to yell "Surprise!" and walk out the door (if at her house). if at your place, simply send her on her way. so degrading.
