It is a sexual move where the male is hitting that
shit from the back (doggie style) and you pretend
like your about to cum. Then, you pull out and spit on her back, but keep the real jizz ready to go. When she turns around to see the mess you made, you
hit her in the
face with all of your next generations (sperm). Laugh it off then get a sharpie and draw a swastika (fuck if i know how to spell) on her lower back and put a tally mark below it. Now, everytime you
fool her, stick another tally mark under the symbol. So now when you see a girl with a bunch of tallys, she either likes it, or is a dumbass mother fucker.
