Probably one of the body's weirdest functions, besides thinking i suppose. I mean it's a noise that can't be controlled except for held in, but i mean you can't control how your laugh sounds. Like it's made up of a bunch of different sounds that come from air that vibrates your voice box with weird wave lengths. All of a sudden your laugh will change unannounced and sometimes that change will include a strange snorting like sound that is truly bizarre. Then some people have that unnatural
sawing sound laugh like really fast breathing, it's like there hyperventilating. Then, usually when your tired, you get a fit of laughter that won't stop and that just kills your gut after about a minute and forces yourself to fight for air. When the laugh finally stops, any word that exits another person's or your own mouth causes you to brake back into that fit of laughter.
ps. my sister just snorted with laughter
