THat was an old joke, if you ask if your cool you likely are not and in real life ask someone that in a manner like a kid asking his father if he's a big boy. You'll get a what the fuck look but you'll make them forget what was stressing them out. My favorite one is if some asshole goes are you a fucking queer or something "we have tons of assholes like that" and I'll look at them and say loudly "I wish" . Then they can't decide because if your not your straight but straight people do not want to be queer. It kind of makes them look stupid for not having a comeback that is funny as all besides "well I thought you were" and that does not get them any burn points back at all, then they are pissed that the guy they tried to insult tossed that grenade of a joke right back at them. Many want to start a fight because they are bigger or just mean but when I do that it's like an indirect challenge to their pride by not responding in a way that will allow them to start a fight but instead look petty if they were to attack me.
