An idiotic mistake that only a member of the male species is capable of making.
Girl: Does these pants make me look fat?
Boy: Well, uh, they don't make you look skinny.
Girl: You think I'm FAT?
Boy: What? I just said they didn't make you look skinny!
Girl: Ugh, you think I'm fat! I need to go on a diet. *runs away crying*
Boy: But I don't think you're fat...
Girls watching nearby: He should have just told her that the pants didn't make her look fat. What a male fail!
