One time I was at a party and had the hiccups real bad,this chick I knew walked up to me and put her finger right in the middle of my chest just below my windpipe and the hiccups stopped.
She pushed it real hard I was like WTF??
She said its a pressure point for the diagram or some shit it works.
You don't even have to have a cool chick to do it to you you can do it yourself.
