There's nothing called a perfect pick-up line. Men always have to face the risk of rejection.
I'm sure I've said some pretty bad pick-up lines.
I don't think I picked up the guitar in the first place as a way of getting women. There are probably better ways of doing it.
I'm not really a line type of guy. I mean, pick-up lines work for some guys. You gotta really sell that thing hard. I did try one pick-up line, and it failed miserably. I thought it was really funny, but the girl didn't find it very funny.
Don't use a pick-up line.
Most high-level models that I've ever met are actually well-travelled; they're cultured, and no guy laying a cheesy line on them is actually going to impact their world.
I will confess I am a great wingman. Since I have a girlfriend, I'll start the night with her, but then I'll help out the guys by making them sound like the most incredible guys in the world.
A lot of my audience is aspirational as far as getting girls.
I don't do chat-up lines. Girls often tell me I'm cheeky. Being cheeky seems to work OK for me.
