I hug all females on GP upon greeting/meeting. It might be the southern gentleman in me, but IMO it's rude to shake a lady's hand/not hug her on greeting. Unless it's like a interview for a job or something or your manager, women get hugs.
I feel ya cuz i'm down south too but it's far from the norm to just go around hugging EVERY chick u know ALL the dayum time. Idk he's an older cat too and to me it just looks like he's in it for the attention whoring and to feel like he still got it...a "look at me i'm the man" move. We work in a factory so he sees alot of these chicks on the daily and hugging them every now and then i could maybe see but almost every dayum time you see them?? Like i said tho chicks eat that shyt up so i'm starting to see it has its merits
