"Never be at a loss for words: 'Hooah!'
Popular Army word defies definition"

Basically, "Hooah" mean everything but "no," and sometimes even that.

I remember back in Army ROTC, how Hooah we super-Hooah, high-speed Hooahs could Hooah all the Hooah Hooah way while Hooahing in an un-Hooah-believable, very Hooahly manner.

I think that was all eight parts of speech.

Hooah?

Hooah!
