shart and dart 

is when you try to fart, but instead you shart and then quickly run to the restroom to clean yourself off.

I ate a Royal with Cheese last night and went to the school dance and committed a shart and dart when I was dancing with Tiffany.

shart and dart 

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".

Mitchell: "I farted in front of my girlfriend for the first time yesterday. She tried to reply with her own fart, but then ended up running to the bathroom."

Kevin: "Ahh yes, the ole shart and dart."
