Well, I didn't use any lyric as a pickup line until I actually got the courage to pick up women :D
I don't know why, but I immediately got the idea of using a lyric to pick up women...and I found many lines here pickuplinesblog.com . However, not all of these lines were from lyrics...BUT THE BEST ONES WERE...and they worked for me...I don't know why. Maybe it was a placebo effect but I think that it worked cause I believed in them
