look up any word, like donkey punch:

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.
