When somebody is such a woman that they need to not just man up, but Man The Fuck Up. Can be shortened to MTFU. Usable on both genders and all species. Also, note that someone who gets some supresses the need to have this for a few days as they have already Manned Up enough.
Ed: Wow, it's reallt bright outside :)
Dude: Man Up Ed.
Ed: No, look, it's so bright, lets go and play outside.
Dude: Ed. I'm going to say this just once. Man The Fuck Up!
Dude: Man Up Ed.
Ed: No, look, it's so bright, lets go and play outside.
Dude: Ed. I'm going to say this just once. Man The Fuck Up!

When a female tries to man the fuck up but cannot do so because she is just simply not man enough, all she can do is what any self respecting lady would do and bend over to recieve a man up her ass.
