lagerboy
A guy who thinks lager is the only drink worth existing for. He probably lives in a shed and wears a tracksuit.
My boss is a lagerboy. He once told me that wine is for posers.
I went to the bar with my friend, and he was a lagerboy. He drank 12 pints and still said he was fine.
The lagerboy in our group tried to convince me that lager is the best drink ever. I said beer. He said I was a traitor.
