With a good comeback, I try not to include physical traits there, as they are easy to come by, and are actually cheap.. this hairdo, and fat s**t....
Take her, as a person - isn't that what they all want??? - and comeback on that... Like,
"I thought we were civilized people, not a one celler!!!"
If two girls, and the one you are hitting on is rude,
"Hey, I am trying to play the ncie guy here (this directly implies you are not one.. have seen it work), so you could behave decently.. Or did not your momma teach you manners??"
The other one, which is not rude, you turn to her and go,
"I wish I had met your mom, must be a great woman!"
That hits!
Maybe something like,
"I see, you're shallowness tells me your genes come from oranges..."
Etc etc...
Three girls, one frien talking to one, so I turn to the big boobed girl,
"Hi"
"My boyfriends over there"
"So, I am talking to you, am I not? didn't occur to me that you were of the type of woman not capable of having decent conversations with men" - she was bit**y on me, possibly cos I got a reputation in that bar...
"No, am not"
"Fine" - turn to the woman beside her and tell her
"And you? Capable of having conversations?"
"I will go the way she went"
"And I don't talk to women who have no ideas of their own"
And turn...
Interesting is that the second girl was eyeing me all the time after that, and I unintentionally ****blocked my friend hitting on the third...
