Fucking lame-o scientists studying some bullshit about how women have more pain receptors in their face or something and how men tend to find pain as a sign of weakness and don't acknowledge it so they have less receptors or something...

it's pretty retarded. Scientific study isn't always the best bet, there are always stupid bitches who deserve to be fucking hit but you can't do it no matter how much you want to. Even a tap would sometimes make them pissed off and accuse you of hitting, or they'll be like 'that's it' and continue the pussy thing. I hate when a girl comes up to me and is like 'do something then'. They know they can't win any fights, but they know we can't touch them.
