When you are getting ready to do a girl from behind you take a slightly warmed
hot dog and stick it in her vagina instead. You then declare "It's in there!" then you
sneak out of the room and wait to see how long it takes until she notices that
it's not you.
Chris: I totally gave my girlfriend the
franking privilege last night!
JC: Was she pissed when she found out it was a hot dog?
Chris: Yeah, but then I
face fucked her and told her to shut up.
