Beer Ponce
Someone who enjoys (and will go to great lengths to seek out) real/craft beer at the expense of substandard, mass-produced fayre. They will often denigrate popular beer brands and judge the character of a person based on the ales they drink.
"Don't get Big Steve a Carlsberg - he's a beer ponce and will think you're a generic knobhead. He'll get apoplectic if you unironically say 'Carlsberg is probably the best beer in the world' - so get a pint of that 'Monk's Relish' porter instead"
