Kihap!

Kihap means "a loud yell" in Korean Martial Arts. The Japanese equivalent is Kiai, in Karate.
So why is it that some people actually say "Kihap!" or something like "Kiiaa!" when they strike? No one said (or did they?) that you actually have to use that word...It sounds really silly to me. The following site actually lets you hear a good kiai and a bad kiai!! hahahahahaha

I don't know if it's good or bad...I really don't care, but please don't say "kihap!"
