four-wheelin in the backcountry

Butt sex. When a guy sticks his penis into a lady's ass hole. The penis usually ends up covered in poopies and generally quite dirty. this is where the expression comes from. Cuz usually if you go 4 wheeling in the backcountry, your car will end up covered in mud. Mud resembles poop and the car is a metaphore for your penis.

Female Infidel: OMG! Timmy was so horny last night but i was on my period. I let him go four-wheelin in the backcountry. It smelt like poops and now i cant control my sphincter so i wear a diaper.

Infidel: I went four-wheelin in the back country yesterday. Ass hole is the second vagina.

Wolf nibbling at the back door

A sweating and itching condition caused by walking fast on hot days or by engaging in any other physical activity that makes your ring sting. Excessive pounding on the missus' rusty sheriffs badge with the wolf having recently nibbled at her back door may cause bleeding and discomfort.

Sharron: Fucken hell Shane, you've been hanging outta my ring all night and now there's a Wolf nibbling at the back door.

Shane: Sorry love, I was drunk. Tell him to piss off.

knocking on the back door

During anal sex, the person that is doing the penetrating and thrusting is the one that is doing the "knocking," and the anal opening is, obviously, referred to as the "back door."

When Eric and Amy are in bed, he's always knocking at the back door.
