People do it ALL the time at clubs and parties. Hell, I've had it done to me a few times (I'm assuming the girl went to HIM).
I'm a male !@#$% too, then? Half the population are male whores (in your opinion). People make mistakes, this incident could clearly be forgiven seeing the picture. It was a 21+ concert, Neo.
"How was I to know she was under age, in a 21+ and older club they say."
I'm not saying he's NOT a pervert and whatnot (because I do not know), but you're just being unfair.
I am not saying he can't be forgiven, if I were to witness one of my friends 'dancing' in this peculiar way I'd probably just laugh and tell the tale so others would know and be amused by it as well. Seeing your intoxicated friends do things you know they'll regret later on with strangers is pretty !@#$% funny. Would I consider doing such a thing a whorish act? Well, considering these people were probably not in love nor knew each other at all, I'd say yeah.
Also, if you hook up with someone you don't get to know first, you know that there is a chance of getting into trouble. Your girl for the night could actually be involved in a relationship, donate some Pfeiffer disease or an STD to you, actually trying to pickpocket or - of course - be under age. In my opinion, Akon took the risk and had bad luck. That makes it his fault.
And lastly, I don't really hate "male whores" altogether, so there's no need to feel offended. I just believe most rappers - including Akon - are a very annoying and superfluous breed of mental patients who have no respect for women, manners and society altogether, hence why I said "!@#$% male !@#$%". He deserves the insult.
