a Bernad
A person who yells at everything and drinks so much they might as well be a human beer barrel!
My uncle is a Bernad. He cursed my dog and drank six beers before noon.
At the party, the DJ was a Bernad. He drank straight from the keg and screamed at the beat.
My neighbor is a Bernad. He told my mom she looked like a used sock and then drank the whole bottle of wine.
