How do I start talking to girls over fb/twitter?

[Unknown Character...]

Ok, so I wanna start talking or even flirting with this girl I like. I wanna talk to her online, so it'll be easier to talk after when I meet her. I've talked to many girls before, but they were only friends, and I wanted to keep it like that with them, so I didn't really think nothing of it. Most importantly, how do I start the conversation, I don't wanna say hey/hi, and what are the things I SHOULDN'T say to her. I'm very attracted to her and would love to ask her out someday in the near future

Talk to her like she's your friend? She's not your girlfriend (yet) so don't treat her any different from all the other girls and you should get on fine.

First of all, get some pictures of you with some beautiful women on your fb. Women love guys that have other women in their lives.

Start by commenting on a few of her comments of pictures. After some back and forth message her. Be upfront and speak your intentions. Be like, "Hey, you seem cool, lets hang out."

Every guy has been in the same position at some point in his life: He sees an attractive girl and wants to strike up a conversation, but he's just too afraid or nervous to waltz up and jump right in. The more beautiful the girl, the more difficult it is; but for a great many men, just talking to any girl he doesn't know can be an ordeal worse than giving a public speech. This need not be the case, however, because once you know a few rules of thumb, there is no girl in the world you can't approach.
