I drink too much beer. Actually wait, what am I saying? I love beer. Anyway, I don't typically drink out of cans unless it is someone elses beer, or it's a good beer out of a can. (Which lucky for me a local brewery cans dank beer for those river trips)...anyway...I have done that oil on your face trick, like when you're trying to conceal your beer in a water bottle...gets super duper foamy. Hate that shit.
