Yeah Mukester post is spot on.
I just realised I do something that seems to work well in most situations:
If someone taunts you in any way, just look at them and say "Thanks" and smile. Maybe even give em a hi-five or thumbs up. Normally does the trick. Even gets a laugh sometimes, esp when done if a girl is testing you.
With my close friends I like to use "Hey man, you say the nicest things" - used that today
If some is being sarcastic towards you e.g
"Hey man, that hair cut is soooooo cOOOOOOOOOOOL"
Just take it literally and say "Cheers dude" and smile again. Completely takes them off balance.
No need to try so hard, cos at the end of the day, i dont really give a sh1t what they think anyway. heh.
If someone is really pissing you off, stare at them until they look away. If violence aint your thing, just walk away. If anyone asks, he wasn't worth the time or energy.
