When a girl is about to give you a blowjob, and you pull her skirt up over her head so it looks like you're doing her doggy style.
"Way to go man, I saw you fucking that girl last night!" "Nah, only head." "Really, it totally looked like you were taking her from behind." "That's because I gave her the old 'Dirty Skirty'."
