pintluck

A gathering to which all attendees bring a (usually alcoholic) beverage. Similar to a potluck, but for beer.

Jill: "Hey, want to come to a pintluck tomorrow? We'll all bring a 40 of nice beer to share."
Jack: "Sure thing, but what if we get hungry?"
Jill: "That's okay, it's a potluck too. See you at 7!"
