A pick-up line is a conversation opener with the intent of engaging an unfamiliar person for romance, or dating. Overt and sometimes humorous displays of romantic interest, pick-up lines advertise the wit of their speakers to their target listeners.
Pick-up lines range from straightforward conversation openers such as introducing oneself, providing information about oneself, or asking someone what their likes are[1] to elaborate attempts including humor such as "If you were Spock's phaser, you would be set to stun" or "If I could rearrange the alphabet, I would put 'U' and 'I' together". Also, they can be to flirt, such as "Do you have a map, because I keep getting lost in your eyes." There is a question whether pick-up lines work efficiently.[2]
