When your girl is on her period and she tells you to take the backdoor but you slip it in the front to use the blood as lube before sticking it in the back, and when you pull out, your Griswold is all Rusty lookin' from blood and shit.
"Yo, I heard you through the wall last night. She sounds like a good ride."

- "Yeah man, we were throwing down all crazy and she said I'm bleeding so take it on the back. I didn't even think before I got a Rusty Griswold"
