Beer Cow 

A technique used primarily in convenience stores where a person imitates a cow at the cash register when they don't have enough cash to pay for what they're buying.

Sh*t man, we pulled a f*ckin' beer cow! The guy at the register was all like scared and sh*t. F*ckin' hilarious man!

the cow of the beer 

The last sip of beer. It is considered by some to be bad luck to drink.

Hey can you bring me a brewski, all I've got is the cow of the beer left?

Cowboy beer is beer that has been through at least one set of kidneys. A cup of beer piss, to be blunt. Thrifty cowpokes have long known that one can fill up their mug on the cheap from an unflushed toilet or urinal in a beer-sloshed country/western bar. Odds are good that drinking this "cowboy beer" will make the drinker tipsy. Studies say that alcohol potency is increased when passed through a set of kidneys, so grab a mug, buddy!

Trey left his wallet at home, so he drank cowboy beer all night at the honky bar, listening to 'Achy Breaky Heart' on the jukebox.
