A completely unexpected fart which is not allowed to completely be expelled. Instead, immediately and conscieously cut off by the ass cheeks Thus, making a "snap" or brief, high pitched sound.
"She tried to pretend it was her shoes but I know damn well that Matilda from the accounting department let a snap fart in the lunch line!".
