The title sentence is a dialogue from "Friends" (the sitcom):
Monica has become acquainted with a man named Paul. On a date Paul says to Monica: "Since my girlfriend left me I haven't had sex with any girls for two years" (of course he was lying for attracting Monica's pity) and Monica believes him and pities him. And then one night she invites him to her home and … Then when Monica finds that he is a liar, she tells the story to her friends. Joey (Monica's friend) says laughingly: "Of course, it was a line".
In the "a line", is "a" an article or something else? And what meaning does "it was a line" have?
Best Answer
I assume Joey meant that this was a pick-up line: something you say to someone to attract them - something that is not necessarily true or meaningful in any way. IOW, it is bait.
To pick someone up is to get them to go out with you, have sex with you, etc. In British English the more common expression is probably chat someone up.
