I know a guy who I would say is below average looking, doesn't have a good personality, and doesn't seem to have much game. Despite this, he tends to be successful with girls. I've asked a couple of my female friends that know the guy what makes him attractive. They've both said that he is "charming". When I ask them to elaborate, they say, "You know, charming..." Can anyone here tell me what it means to be charming?
