A funny story, one time during a small class, a young gentleman kihaped and burped at the end,  it's sound funny and unworldly.  He was embrassed but I told if he could do that on command he would scare anyone.

if that applies to both 'ends' then the kids in the youngster's class here would frighten you to death! you can't help feeling embarrassed for them but they just dont care! lol

hehe. I just came back from a tournament. got first place high red belt. Broke a kid's nose hehe. Well my yell in tournaments is like "ehhhhhhhhh!" but when i am kicking a bag or a target i yell like "bahaaaaaaaaa!"

ok, i probably have about 9 kihups total that i use within a week. it just depends what im doin and where it is. most of my yells are tweeked versions of my instructors yells lol. so i have like: huss, iits, hassa. bassa, hup, sut, hie. as far as i know the kihup just needs 3 things, sound, exhale, and tighening of the abdomen/dan joon. i just get tired of the kids/new students saying "kihup" for their kihup. to fix it, i just explain to them that their yelling "yell" and i let them see how silly it sounds, so then they get a better yell.
