Are you a shit lock or a master key?

I just had an argument with a girl I know. She was saying how that it's unfair that if a guy fxcks a different girl every week, he's a legend, but if a girl fxcks say two guys in a year, she's a slut. I explained to her that if a key opens lots of locks, then it's a master key. But if a lock is opened by lots of keys, then it's a shit lock. Moral of the story, don't be a shit lock :)
