A couple cheesy pick-up lines are: "I'm not a photographer, but I can picture me and you together" and "Are you religious? Because you're the answer to all my prayers." Another cheesy, clever pick-up line is: "Being without you is like being afflicted with the Cruciatus Curse."
Pick-up lines are cleverly worded compliments put together to express romantic interest. They can also be used for humorous purposes. The pick-up line about the photographer and picturing the two of them together is a clever pun using the word "picture." It signifies a photographer's picture as well as metaphorically picturing the two of them being romantically involved.
A couple other cheesy pick-up lines are: "Do you know what my shirt is made of? Boyfriend material" and "If you were a vegetable, you'd be a cute-cumber." These lines once again make use of double meanings to get across a message of affection.
Other pick-up lines can make use of popular culture references to increase their relevance and humorousness. The aforementioned line about the Cruciatus Curse references popular film and book series "Harry Potter." In this series, the Cruciatus Curse is an illegal spell causing the victim to experience torturous pain. The pick-up line achieves heartfelt humor by implying that the pick-up artist feels tortured without the adored love interest.
