From the Drowsy Mind of a Mouse

I was driving down a road with my girlfriend to some place for a date when she mentioned that men were tired of shrinking. It was an extremely short fragment. Now, it didn't seem like "shrinking" was referring to shrinkage (in case you don't know what that is, it's when your pee pee gets really tiny after putting it in cold water), but rather the physical act of a person shrinking in size. I don't know, it didn't make any sense.
