I was devastated yesterday in karate, when one of my teachers told me that "Kia!" actually means, "Yell!". He was like, "You can't yell 'yell' when you go to competition, the judges will laugh at you." So I said, "But I like yelling Kia!"
"You really shouldn't do it," he looked at me.
"But, won't some of them find it ironically hilarious?"
"Nomatter how good your kata is, they will think you don't know what you're saying."
"So then... what should I say?" I said.
"Try to make it more gutteral, from your diaphragm. Like, Soueoueouw!" It was like a constipated Conan the Barbarian.
"Soueooaaaioow! That does not sound right!" (I commence all manner of vowels jammed together to make my own scary noise while flexing my muscles in the mirror, to no avail.)
Funny, I don't usually have much trouble finding expletives.
