I was told that when I had the hiccups, the best way to get rid of them quickly was to scare them away! It is a little difficult to be scared when you are expecting it, but the idea is to somehow have someone startle me enough to get rid of my hiccups.
I was originally told this trick by my older brother when I was about seven. I had a really bad case of the hiccups and I was almost in tears. My brother really liked to give me a bad time, so I think that was part of it. It did actually work the first couple times I had the hiccups. Then I think I expected it too much and it stopped working.
Kyla said she thinks this might have just been a way for her brother to screw around with her. I dont know very much about hiccups, and have never tried to have them scared away, but it doesnt seem very plausible to me.
This could be related to a form of shock treatment. Some native Americans would alternate between sitting in a sauna and jumping in a ice cold river because they thought it was good for their body. Likewise, it could be believed that a sudden jolt would cause the body to change enough to stop the hiccups.
