It's certainly not practical but then again, how many chicks do you see with those little signs on their myspace

? Maybe 4 years ago when myspace was in it's prime, but it's a rare feat now and when the chance arises and you definatly want a response from the gal in particular then this is the way to go.
You can't think of online game as being a club mainly being, in a club people will pay attention for as long as you're interacting even if you are the worst pua in history. Online, they can read and exit from that message after reading a sentence never to give it a second thought. The responses vary of course, some play along, some think it's nerdy but get a laugh from it and typically want to know who you really are... From there you can roleplay for an extra message or two: 'what features of mine developed your unhealthy obsession over me' after that message, DHV and false disqualifier and then you've got the cat in the bag
If anyone tries/is trying this, tell me how it goes!
