splashback nugget 

So a splashback nugget is when you shit out a fairly large poo then after the impact of the fairly large poo hits the water, there is a splashback which while your straining out your next poo, the splashback then causes your bum hole to tense which then cuts off your 2 load to a much smaller nugget which is named the splashback nugget

Arr mate I was shitting out a huge poo then splashback nugget happend.

Splashback Enema 

When a dense drop jets a puff of water upwards fast enough to enter the sphincter before it closes from the release.
This requires very specific conditions to occur, and consequently is a rare but possible event

Well boys, it finally happened. I just received a splashback enema. As if that wasn't bad enough I had toilet water overflow from the invasion site dripping down my cheeks.

Splashback Arrester 

Layer of toilet paper placed on top of the bog water to stop a splash soaking the arse crack from a falling turd. Guaranteed to prevent a Splashback Enema. Phrase derived from a device used in gas pipes called a Flashback Arrester to stop explosions.

Hey Stu, thanks for telling me about the Splashback Arrester, I did a hefty shit and for once I didn't get a jet of cold pissy bog water shoot up my arsehole.
No problem dude, glad I could help!
