LMFAO @ this Thread!
first of all, dont be scared she'll reject you. talk to her like you know her. bring up some observational humor or something, introduce yourself (if you havent met). if she continues to talk to ya after a while, she likes ya and isnt just trying to be polite. laughter is a GOOD sign, even if you're NOT funny, most girls will giggle and be laughy if they like ya, or actively ask questions/contribute to the conversion and not just answer you. toward the end of the convo, tell her you liked talking to her and ask for her number and if she'd like to talk again. dont just ask her out on the spot i.e. "hey girl, you're hot. wanna go out with me?" thats retarded. also helps to not ASK her if she wants to go out or ASK for her number, SUGGEST IT. like say "why dont ya gimme your number, i'd like to talk again." or "we should go out sometime".
DO NOT START OFF AS FRIENDS. that how you get "FRIEND-ZONED". make sure she knows you have more than friendship in mind from the get go! very important.
