A fork of Rural Dictionary
the phenomenon where an otherwise timid individual has consumed enough beer that he begins shit-talking to anything he comes in contact with and has the illusion that he could defend himself when someone tries to kick his ass because of that shit-talking (i.e. - the drunk grows a set of balls - beer balls); this person's tendency to shit-talk decreases with his blood-alcohol level.
"I could not believe the shit that fool was talking. I'm glad I kicked his ass."
"He was drunk. I guess he had a set of beer balls."
