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.

four-strikes-in-a-row

It's called a 4-bagger or a hambone.
After you bowl a turkey, or three strikes in a row, the next strike makes it four-strikes-in-a-row, which would be called a hambone or a 4-bagger.

a sexual position involving one male and two females, the male is to stand upright infront of a bed or table while a female is facing up. the man is going vaginal on female number one ( on the table or bed) and female number two has her vag up on the mans face and her legs are on his shoulders. female number 2 is faced down kissing female 1 while both of their vaginas are played with by the man. this position looks like a 4 ....therefore..... its a three some making a four....THREE SOME FOUR!

Four Finger Sally

A girl that is so loose that she can't even feel a 9-inch wang in her. She walks around constantly wet willing to give it to anyone willing to have sex. Usually, they are sex addicts and absolutely love the attention they get for acting like such a whore. To be a Four Finger Sally, you have to fit at least 4 fingers in her vagina, but a lot of the time, they can fit a whole fist full and they enjoy it. But sometimes, even that is not good enough for them. Basically, any guy with a penis smaller than 10 inches while erect will not satisfy their needs.
Damn, I just had sex with a four finger Sally. Too bad I didn't feel anything... it was like my dick was in a cave.

five, four, and a door

a residential pile of vomit known as a 'colonial-style' house, characterised by vinyl siding, paste-on shutters, and gypsum board covering every interior wall and ceiling.

Named for the five windows on the second floor, and centered main entry door flanked by two windows on either side. Often, they are accompanied by a paste-on two-car garage which serves as the real main entry door for the house, even though the gas-guzzling soccer-mom-mobile known as an Expedition or Escalade is too big to fit inside.

The cancerous sprawling suburbs of Northern Virginia (NoVA) are the five, four, and a door capital of the world.

The arch-nemesis of architecture.
The domicile of yuppies.
The telltale sign of facadomy at work.
If I see one more development spring up full of five, four, and a doors, I'm going to slit my wrists with my drafting triangle and shove my compass into my eye.
