You should be able to come back with something every time, im pretty decent at "banter" as far as it goes, trick is to a) start the banter at people who banter a lot at any opportunity, if its on your terms its easier to "win". Have some points you know they are a bit ashamed/insecure about (obv dont go too far and properly upset them) at the back of your mind, as banter doesn't have to go with the flow, ie if some says "how well did you do on that exam jim?" after you did poorly you could reply "about as well as it went with you and that girl Tuesday night", (assuming something went poorly Tuesday night), so basically you try and take the banter of out a situation he has you beat, ie grades, into a general case, and because you are actively amoging/ know about pua u are going to have a list of his shortcoming up your selves guaranteeing your look better. I've used this to great effect, to the point that my flat mate who would always make me look bad doesn't even try it with me, knowing ill come back with more witt.
One of the great things i do is keking, this is basically pulling down my flat mates trousers cos he never wears a tight belt, or he wears sweat pants, this basically is a massive amog, and he cant get upset because its "revenge" for what he said before, works so well. In our flat with others around of course, i rarely do it in public because its kinda harsh unless the situations fit. So be imaginative with banter
