When a girl has a moderate to very attractive body, but also possesses a nasty-ass face that detracts from her entire attractiveness. You and your boys therefore declare that she is a 'BHF', meaning that you would tap that ass but try and avoid making eye contact while doing it. BHF's are acceptable to hook up with when you are drunk, but otherwise will net you a penalty of 10 Man Points taken away.
Synonyms: "Paper-Bag", "Paper Bag Bitch", "Fugly", "Aw man...if it weren't for that mug..."
