When a guy has sex with you while you're on the rag and when he's done your thighs look like they have the imprint of a bloody butterfly on them.
"Dude, I was on the rag last night and I fucked Johnnie and when he pulled out the insides of my thighs looked like a bloody butterfly, I call it the blooderfly."
