A moment in time when one feels confident to rip a forceful fart. The result is heightened terror from feeling something warm and wet in your britches. Usually accompanied by the need to promptly excuse yourself from the social environment that would normally commend on such forceful farting.
I just shot a shartdart and now I have to choke off my pant legs on the way to the bathroom so I do not soil my socks.
The act of sharting (a mix between a "shit" and a "fart") and then running to the bathroom to clean up your shorts. Sometimes also referred to as "the shit and split", or the "toot and scoot".
