COWTB

This stands for "Cold one with the boys." The term represents the traditional American bro culture of enjoying a chilled alcoholic beverage with a few of your fellow home boys.

Bro 1: "Hey man, what are you doing tonight?"

Bro 2: "Sorry, I have to attend my cousin's funeral."

Bro 1: "That's lame, I'm going to crack open a COWTB!"

Bro 2: "You know, I think I'll join!"
