An act involving 3 willing participants. The first participant removes the lid of the cistern on the toilet and sits in while proceeding to take a nifty little dump inside. The second part-taker sits AC Slater style on the toilet bowl performing fellatio on the first participant whilst pissing into the toilet. The third and luckiest particpant will be kneeling like an alter boy with their lips firmly clasped in a suction grip around the anus while the second participant power dumps into their mouth. To finish the third participant then proceeds to splurge a creamy-corny parcel onto the bathroom floor.
Larry: you should have seen what I caught peter doing earlier. I walked into the bathroom and he was sitting top-deck in the ensuite having a triple decker Blumpkin with with Greg and Sarah. Shit everywhere.

A person who exceeds the usual pre-requisites for being a jerk, and is further characterized by pompous indignation at any inferred criticism. These people are facinated with the smell of their own poops.
Carl, the quintesential triple decker turdpie, never returned phone calls from people he suspected mocked him, and preferred the bathroom to the company of others.

The highest form of house party fuck you like an upper Decker basically but instead it just shitting in the top tank oh someone's toilet you triple in that b****
Example

That's where there's a guy on the bottom fucking a girl in the ass and there's a guy on top fucking her in the vagina creating a triple decker sex-sandwich thus wrecking their peckers.

The most heinous sexual act. So terrible that your friends can never speak to the girl you gave it to ever again. In addition, they are not allowed to be friends with you for a month. At the end of that month you'll still think it was worth it.
Where's Jim been?
I don't know, I can't be friends with him until August since he gave Jane a triple decker peanut butter and jelly sandwich.
Oh my god! That's awful.
