"Pick Me"

I don't understand...I'm looking for friends and yet you all call me a "pick me"? So I don't like skirts and the color pink? I like blue jeans and a t-shirt. Whats wrong with me...After reading you guys's replies i'm starting to think there's something wrong with me. Am I really that bad? Am I a monster? Why am I being treated this way...I just want friends...
