HFC or Hip Flask Crew means a group of people that all have secret hip flasks on them. They're a bunch of alcoholics that think they are cool but they aren't, they're really just cheapskates who don't want to spend a fiver on a beer at a festival
Look at that hip flask crew over there. They're so drunk.
