After ejaculating in your girlfriend's face, pretend to wipe off her face while actually rubbing your load into her eyebrows, causing them to appear to be white, like Santa Claus. Then sit on her lap and tell her what you want for Christmas.
Guy #1: How was your date last night?
Guy #2: Tits. I gave her the Santa's Eyebrows.
Guy #1: No way! So what are you getting?
Guy #2: I asked for an iPad, but I'd settle for a Mac.
