I take no credit for this awesome joke filled to the brim with sexist critique. If you can’t laugh, you probably didn’t find Mulan (Animated) racist.
So one day, a girl casually mentions to her group of friends, “Society’s full of double standards! I mean, if a guy sleeps with more than ten women in a month, he’s a STUD! But if a lady sleeps with more than two men in a year, she’s a SLUT!”
Everybody agrees with this widely regarded social truth.
Until the mild mannered bloke in the group retorts, “Think about it this way. If a Key can open any lock, it’s a MASTER KEY. But if a lock can be opened by any key, it’s a LOUSY LOCK!”
