beer festival
1. A festival where the promoted theme (eg. a popular brand of beer, folk singing, medieval banquet, striptease, Octoberfest) is blatantly ignored, and large quantities of beer is drunk. And people roll about rat arsed, pissed as a newt, lit up like a christmas tree, and display a range of loud and disorderly behaviour.
I went to the (insert your favourite beer) Beer Fastival and had a great time!
