When a guy injects his penis into the anal opening and has sex with it for a long period of time, well the shit noodle is what comes from the tiny little whole in this penis the next morning. It's literally a noodle of shit.
Poop- "HOLY SHIT MAN, HOLY SHIT, I CAN'T FIT IN THAT LITTLE HOLE DUDE, I CAN'T FIT."
Man- "GET OUT POOP, GET OUT. YOU'RE HURTING MY SHAFT."
Poop- "I GOT IT. SHIT NOODLE FORM. I'M NOODLIN' OUT."
A shit noodle is where you have recently had chinese noodles and a curry at the same time. This as we all know would rupture your bouls causing a explosion of shit. "Better get to the bog quick" Basicly when the shit comes out the corn hole it will be all stringy like noodles and have the smell of a curry and although this smell might be tempting please do not eat, unless you like shit noodles then eat your ass off.
My god thats a big shit noodle.
Well spank my ass and call me a shit noodle.
