Cackler

[Cami]

The act of laughing [loudly] and being a dumbass about it. It hurts your ears and makes you [curl up] into the [fetal position] asking for your mother.

[Monty]

A very loud, drawn out fart with the peculiar sound made by [flatus] [vibrating] through ass cheeks in a [flapping] manner.

[Sommer]

Similar to the [Dirty Sanchez] the cackler involves the act of anal intercourse, leading to [excavation] of feces via the penis, which is then applied on to the uppper lip in the form of [a Hitler] style mustache.
