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."

Name for an ugly, loser who starts dating a really hot girl because she has settled for him and ends up thinking he's too good for her.
"I'm dating Jon, he might not be all that attractive but he's a super nice guy who's totally into computers."

*One week later*
"He's a super lame guy who ditches me on the daily"
….
"I'm dating a shit noodle"

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.
