You drink beer in them. You spill beer on them. You wear them once a year, in a crowd in which you are almost guaranteed not to be wearing the most hideous thing.
They should not be understated. They should have as much orange as possible. It should be absolutely incomprehensible to wear them anywhere other than their intended venue. Not "slightly weird," not "fashion blind." Absolutely incomprehensible.
Mine is nice; I'm not saying it's not. But nice is not an appropriate descriptor for something called a "beer jacket." "Beer jacket" cries out for bold and unapologetic eye-destroying ugliness. Get it together.
