I think the theme should be Pirates vs. Ninjas.
Everyone attending has to dress as /either/ a PIRATE /or/ a NINJA. There is to be NO conversing about who's coming dresssed as what. Then on the day whichever lot has more people (that is if there are more PIRATES than NINJAS or more NINJAS than PIRATES) gets to make the other lot (PIRATES or NINJAS) buy them beer.
Failing that I suggest a Hello Kitty theme. I'll be the humiliated one in the corner.
The noises commonly associated with flatulence are caused by the vibration of the anal sphincter, and not by the buttocks. The sound varies depending on the tightness of the sphincter muscle and velocity of the gas being propelled, as well as other factors such as water and body fat. The auditory pitch (sound) of the flatulence outburst can also be affected by the anal embouchure. |
