Like a turnicate to block blood from an area the turdicate is when you tighten your belt as far as you can to stop a turd coming out. It is usually used when you need to take a dump but something of importance is happening. It can also be used mid-dump so you get up and do it so it doesn't bother you. It can be risky though, sometimes it squeezes the crap out.

Get the Turdicate mug.
A turd that has more fat at the top than at the bottom that floats in the bowl in a vertical fashion, looking like Mr. Hankey.
I had a cheeseburger and a salad last night and this morning I shat out a turdical.
