Motives of the attacker, or awkward hug giver range from just messing with his friends or actually initiating contact to vent pent up homosexuality because he is still in the closet. Both cases are easily identified, the first is characterized by laughter and little awkwardness after interaction. The other is more awkward than normal awkward hugs and the giver could not want to let go or be unable to laugh his actions off.
