What is the meaning of cheesy pickup line?

A cheesy pickup line is a trite, cliché, or overly exaggerated phrase used to flirt or initiate a romantic or sexual conversation with someone. These lines are often seen as insincere, unoriginal, or even humorous due to their lack of creativity or genuine effort. They are typically used in a light-hearted or playful manner, but may not always be well-received by the recipient.
