According to a study in the Journal of Personality and Individual Differences, researchers examined three different types of pick-up lines and found out which type was most effective. The different types of lines included:
Direct - "Want to have a drink together?" You have really nice eyes." "Can I have your number?" "You're cute."
Innocuous - "Can you recommend a good drink?" "I've seen you before, do you work here?" "Where did you get that tattoo? Did it hurt?" and "Hi."
Flippant - "Shall we talk, or continue flirting from a distance?" "I always see you here, you must be the bar's best customer!" "Since you're alone and I'm alone, why don't we sit together?" "I'm easy, are you?"
The study found that being direct and to the point had the best results. Arden Leigh, the author of “The New Rules of Attraction,” agrees telling The Doctors, "It takes the guesswork out of it when you convey your intentions clearly. She also notes that men find it refreshing when they get picked up on and enjoy being seen as an object of desire. She feels at the very least, the person doing the picking-up will leave the moment with a clear idea if it worked or not.
Arden urges potential female suitors to stay away from canned lines that we've all heard before. Instead, she feels keeping it organic and honest to the moment will be more effective. She says to use something like, "Hey, do you know a good pizza place around here?" Or a line like, "I'm looking for a new podcast, do you have anything you can recommend?"
And her favorite type of pick-up line involves the use of a sincere compliment and identifying what is compelling you to be attracted to the person and then incorporating that into the conversation. For instance, "You have amazing energy. I noticed how you go out of your way to include everyone in the conversation... you look like someone I would like to get to know."
