A sex move that is like no other. I, Carwash7576, am inventing a sex move. Kinda like a gang bang, but not really. There has to be 3 people there, at least 2 males. One male on the left side, one male on the right side, and they both jerk off at the same time in a speed test, and the third person is waiting for them to orgasm while doing their own thing. When the 2 males are about to orgasm, the third person runs in the middle, and gets a “dirty car wash” the person running in the middle, has to go back and forth between sucking on the dicks after the initial carwash. When the 3rd person is sucking on the dick, the other dick goes inside. It ends by putting your clothes on, walking out, and acting like it never happened. After the dirty car wash takes place, it’s never spoken of again, and you will never be the same. Ever.
Girl one: “Ew. Why do you smell so bad?”
Girl two: “I’m not really supposed to talk about it, but I did a Dirty Car Wash with Kyle and Chad.”
Girl one: “Oh shit. No wonder you smell like fish.”
Girl two: “What the fuck? The Dirty Car Wash is the best thing i’ve ever done!”
Random girl: “The fucking what?”

A drinking event at a party that usually involves group effort (preferably 10+ people) . The person getting a Tijuana Car wash is referred to as “the Car” . It starts by one person(the car) laying on a long table. Two volunteers hold onto a arm on opposite sides of the table dragging “the car” across on his/her back. While the rest of the party stand on each side of the table pouring drinks & shoving snacks into “the car” mouth while they are being dragged across the table on their back. When “the car” reaches the end of the table they are greeted by the biggest breast woman at the party who will then pour tequila into his/her mouth then shove a lime down “the cars” mouth.
Person 1: WHO WANTS TO DO A TIJUANA CAR WASH?!

Person 2: I’ll be the car!

*person 2 is then thrown on his back on a table while the party preforms a tijuana car wash*
