Nobody wants to feel like just another person of some list - the thing about pick up line is that they are general enough to suppose to attract anybody, which means - they usually attract nobody.

Don't use pickup lines - introduce yourself and  start a conversation.

In the dating \ going out scene you'll get a lot of rejection and be judged for your look no matter what you do, just don't take it personally.  Also, I think that the chances of meeting a potential partner in a bar \ street \ wherever pick up lines are necessary is pretty useless - I believe that the best way of meeting someone is to get to know them as a person and let a relationship built up from friendship.
