Dirty Thirty

A case of Keystone Light beer. 30 cans... Popular at high school and college parties because of the beverage's affordable cost in comparison to other beers. The term "dirty thirty" was coined in reference to the beer's lackluster if not downright "dirty" taste, and quantity of 30 cans of beer in the package. Despite its shortcomings, eager drunkards across the great u.s. of a. are willing keep their costs down on the shillings to shitfaced (s.t.s.) ratio scale so that the former number can be achieved for a lower price.

"Hey Tom's house is open tonight. I'm going to swing by the Shell and pick up a dirty thirty."

dirty thirty

A sexual act performed by one girl, thirty guys and a merry-go-round. To do this, the girl kneels on the edge of the merry-go-round and the merry-go-round is given a swift spin. As the merry-go-round spins, the girl then gives head to each male in the circle, creating a seemingly endless circle of blow jobs.

Dirty thirty

The age in which it becomes socially unacceptable for a man to ogle and hit on any female under the age of 20. Its just creepy to see a dirty old man (age 30 and over) salivating over a hot young thing (less than 20 years old)!

It didn't bother me so much when Bill was 29 and hitting on the hot little 19 year-olds, but now that he is dirty thirty, it is just sad to watch.

Dirty Thirty

Someone lays in the pre-anal sex posistion and spreads their cheeks while a very friendly companion pours a double shot of tequila into their gaping void. After thirty minutes of holding the shots inside of their rectum, the companion places their lips around their partner's anus as they fart the shot of diahquila into their welcoming mouth.

My poop shoot hurts from the Dirty Thirty last night!
