How Facebook Killed the Casual Hookup

Yesterday it occurred to me that all the social networking sights have put a major strain on the casual hookup. I'm not saying I got down like this, but remember when you could go out, holla at a girl, participate in some adult activities and never hear from them again? The whole point of the casual hookup is to get in and get out with the least possible knowledge of the other person, while also maintaining your anonymity. Facebook and Myspace have ruined that. The scenario is the same — you go out, holla at a girl and participate in some adult activities — but with Facebook and Myspace you can't say you never hear from them again. Before, you probably wrote down their phone number — even though you had no intentions of calling. Or maybe you did call them the next day to see if they got home ok, or once more just so you didn't feel like an asshole — but you never really wanted to talk to them again. Pretty soon they just became another Beth, Jenny, Dana (bad breath), (Bowlegged) Sarah, Anna (annoying laugh) or just plain "DON'T ANSWER".
Social networking has changed the game, though. You inevitably end up being friends with them on Facebook or Myspace, even though you weren't, aren't now, and have no intentions of being their friend. Like getting their phone number, it's obligatory. Either they friend you and you accept because you don't want to be an asshole, or you friend them because you don't want them to think you're an asshole and they accept because they don't want you to think they're an asshole. Maybe you send them a message to see if they got home ok, or one "thanking" them for a "good time". With the phone, the person would just fade off into oblivion if you never used their number again — just another who the hell is that in your cellphone phonebook. You can't do that with Facebook and Myspace. Whether you care or not, once you accept their friendship you're subject to hearing every boring and ridiculous detail about their life from when they get a new dog to what exactly they're doing at that very moment. You even get to find out when they have a new boyfriend, or better yet, that they had one at the moment you were engaged in adult activities, or even better still, that you're the reason their relationship is "complicated". Unfortunately, you learn more about them from their status updates than you did before you got them home. And it's usually more than you care to know. I don't care what kind of wine you are. I don't even like wine, much less you.
And unlike the phone, you can't just say you don't know them. You're forever attached, if not by the wonderful mutual friends section on your page, then by the pictures to commemorate the whole coup de grace. Anybody who's friends with the both of you knows it. So every time somebody asks you how you know so-and-so, you're forced to relive how you met at a bar, got drunk, hooked up, and how she peed in your bed and told you it was water. Then you have to tell them how awkward it is seeing them on your way to class, or how you got partnered with them for a long-term assignment. Then you find out your friend was only asking because the girl is his brothers girlfriend and he didn't know you knew each other.
Why don't you just unfriend them, you ask? Well, that takes time and effort. It shouldn't take time and effort to NOT be friends with somebody. That's completely contradictory to the way not being friends works. You're not supposed to take action to not be somebody's friend. I'm too lazy to not be friends with somebody, and I'm far too lazy to do it by unfriending people.
