Schrodinger's Shart 

When you are unsure if you farted or sharted, but you're too afraid to move from a sitting position to find out.

Hey man I farted but it smells like a shart. I don't feel anything, could it be a schrodinger's shart?

St Patrick's Shart 

An unusual bowel movement occuring 1-3 days following the annual St Patrick's Day celebration held on March 17th. The bowel movement is most likely due to the overconsumption of Irish culture foods combined with copious amounts of alcohol.

Wife: Why is your green underwear on the bathroom floor and covered in shart?!

Me: Three words: Corn Beef Cabbage...

...And Jamison Whiskey.
Wife: Aw hell naw not the St Patrick's Shart again!

let's not start sucking each other's dicks yet

Don't jump to conclusions, or let's not start celebrating yet. Cautious and borderline pessimistic optimism.
Similar: don't count your chickens before they hatch
Variant: "Let's not start sucking each other's dicks quite yet."

"I just got a letter that said I won a sweepstakes, but let's not start sucking each other's dicks quite yet."
"I just bought PAX tickets on eBay, but the seller had a picture of himself with a neckbeard, so let's not start sucking each other's dicks yet."

shirt shart 

Everybody has a shitty day every once in a while. Sometimes when nature calls one can find that adequate facilities are too far away to be reached in time. In a pinch, you can rip off your shirt pocket and use it to wipe your ass when no toilet paper is available. A SHIRT SHART is the process of crapping and the using your own shirt pocket to wipe up.

Yeah, I got caught up in a shirt shart yesterday. We were fishing at the lake and I had to take a dump. I gotta go to Old Navy now to replenish my wardrobe.

Shart Sausage 

An extreme form of your usual Shart or even more extreme Mudslide. A Shart Sausage occurs when your butthole is so loose, what you believe to be passing wind turns out to be a fully formed bottom log implanted directly into your underoos.

Example

Dude #1: "As if my life needed to be more embarrassing, I totally just let go a Shart Sausage."

Dude #2: Seriously?! Did you leave your buttplug in again? How is that possible?

Dude #1: A cursed combo of Indian and several ounces of cheese...
