Everyone laughs. It's how we make life fun. Because life is funny! While enjoying laughter is universal, no two laughs are alike. Types of laughs can have their own style, which can define the personality of the person who's laughing.
If this is your laugh type you are one silly human. This laugh is soundless at first, but is eventually squeezed out into a high-pitched crescendo. It sounds similar to someone slowly letting the air out of a balloon, only funnier, and more contagious.
