Most of the time I'm pretty good at impressing boys, because, let's face it, apart from the tits and the vagina, I am one. The average guy seems to really enjoy the fact that I can intelligently discuss football and hockey, know positions and formations and who the players are, and most importantly the fact that I never claim to enjoy such and such player because "he is so hot"*. Your nerdier type of guy is usually drawn in by the fact that I can recite the entire original Star Wars trilogy verbatim from memory, or that I'm happy to debate Kirk vs. Picard for as long as it takes to convince you that it is obviously Picard. By the time the conversation turns to sex (and the conversation ALWAYS turns to sex) every guy around thinks I am their dream girl. I'm happy to point out and then join you ogling that girl over there who is falling out of her shirt, after all, that IS an incredible rack! Girls need to be less selfish and uptight: blow jobs and anal sex for everyone, all the time! And did you see the centerfold in Playboy last month? Oh, because I subscribe, that's how I saw it.
The thing is, and here's the rub (heh): the above behavior is the kind of thing that works best in a group setting. When you're one on one it can be kind of off putting in that it comes off as overly aggressive, and when you're one on one with your really hot friend who is so attractive he distracts you and throws you off your game it can be a disaster. Such as when he is nice enough to drive you home and he makes a comment as he's dropping you off about the hilarious squeakiness of your vinyl pants. Answering that statement with a pouty sounding "Well you were SUPPOSED to take them off me!" can quickly make you go from "this girl is really cool" to "this woman is fucking terrifying". I should probably apologize for that. You know who you are.
*Seriously girls who like sports, this is annoying. Stop doing it. I'm not saying you can't think they're hot, but you need to keep that shit to yourself and not bring it up in the middle of a conversation about whether or not the Wildcat can continue to be an effective formation in the NFL now that the defenses are prepared for it (it can't).
