When the diaphram goes FLIP FLOP!!!! And a quite hilarious noise comes out. It sounds like somebody saying HICCUHHH but you know they dont really sound out the P. Hiccups can make people roll on the floor laughing.
Ally McBeal had the hiccups because she was eating too many pretzels, so for them to go away Blake Griffin told her to drink water. But thats didnt work so then Blake tried to scare them away.
