high colonic 

Officially it's an enema to flush out the colon but in the slang it means to literally scare someone shitless, which has the same effect as an enema.

Chrissy in the Sopranos got a high colonic when Junior's thugs took him out to the Meadowlands for a mock execution in season 1.

Colonic Apocalypse

1. A shit so massive it leaves you wondering if you have just had an anal prolapse.

2. When one's defecation is of Biblical Proportions.

John: "Damn, Derek's 'Cayan Chili Macaroni and Cheese' concoction just gave me a Colonic Apocalypse..."

Mike: "Should I call 911?"

Colonic Jihad 

Diarrhea, which is so sudden, massive and explosive that it feels like your bowels have declared a holy war.

About 30 minutes after I ate at the Chinese Buffet I had an attack of the colonic jihad. I barely made it to the bathroom in time.

colonicbag

The new douchebag. Surpassing the original term, colonicbags are much worse than douchebags. Their collars are taller, their cars are brighter, and their parents are richer. If you work in foodservice, a colonicbag will probably throw a crumpled $20 at you.

That guy is such a colonicbag. His collar is up to his ears!

Colonic death grip 

The masterful kung-fu act of suppressing a giant mud rock into a deep slumber using only a well-disciplined sphyncter.

Had a prawn and boiled egg vindaloo last night and its playing up with my guts, luckily I managed to summon a colonic death grip to avoid shitting myself in Asda.

Colonist Shuffle 

A dance performed in Heathrow Airport when first time American visitors to the UK encounter a local pedestrian head-on. The locals try to pass on the left while the tourist tries to pass on the right resulting in a zig-zagging synchronized jig for a few seconds.

"Man, I was so tired when I got off the plane in London, I did the colonist shuffle three times before I got my UK legs under me."

Backyard Colonic 

Backyard Colonic is a hygienic procedure by introducing a stream of water into the body via the anus at relative high velocity with a garden hose. This procedure is typically conducted in preparation of vigorous anal sex session. The first backyard colonic was performed at a hippie’s cabbage patch in

Berkeley, California hence the origin of the name sake.

Mike had diarrhea but wanted a gang bang with a bunch of dudes at the local La Quinta so had a backyard colonic by the parking lot dumpster.
