Using someone else's pickup line, (especially without permission) is a dick move. Only AFC Jerks would do this. It is lame, unoriginal and ruins you're chances of using the same line. That he didn't have any follow up just shows what a dick he is.

The trick is to make the experience unforgettable to her.
A real PUA will make every women he encounters feel like she experience something once in a lifetime.
