Some girls hate pick up lines- but the right ones are funny and good ice breakers. For example- my boyfriend went up to me and said he hurt his knee falling for me, then apologized for the stupid joke, and that's when I really fell for him. So te right ones are good;) like that one.
Pick up lines are cheesy and stupid. They are NOT what a girl wants, nor is that an efficient want to get a girl to like you. Say really sweet things to her and be a gentlemen. Not a guy that is disrespectful and trashy.
