male fail 

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!

Male Fail 

When a man or men fail to prevent bad things from happening and they absolutely could've done something about it.

Letting the #MeToo Movement fester for so long that all men are now branded predators, repeatedly voting for makeup wearing clowns, and allowing the Supreme Court to install George W. Bush without demanding a re-vote are a few great examples of Male Fails.
