The age at which single women without children realise that their biological clock is ticking, As a consequence they may lower their standards and increase their willingness to perform sexual acts as a matter of desperation in order to find a mate/sexual partner.

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."

A drinking game (originating in Upstate NY/Capital District area).

Usually played, just prior, to heading out to the bars & clubs (A.K.A. "pre-game drinking" or "pre-gaming").

RULES: using an egg timer, or clock... every participant drinks a completely full shot glass of beer every minute, on the minute.

This game is used as an easy way to get a quick "buzz"... yet difficult (for some) due to the constant smaller quantities of alcohol, timing, and aeration of the beer.

SEE: "Power Hour" for a longer version of this game.
Person A: "Let's head out to the bars!"
Person B: "No. Let's watch the end of the game, then head out to the bars."
Person C: "I want a good buzz before we leave..."
Person B: "Let's do a Dirty Thirty, then head out to the bars!"
