When you take a dump, and the poo has slid into the shadows of the toilet bowl, and cannot be seen. There's also nothing on the toilet paper when you wipe.
I just came back from the shitter, and I'll be damned if it wasn't a "poodini"...it was quite an illusion, cuz I coulda sworn a little turd slid out!
A turd that just won't flush. The same as a floater but named in honour of the great magician and escapologist Houdini. The only way to defeat a Poodini is to sink it using a magic parachute like piece of toilet roll which drags the fecal matter down to its watery grave.
Meeting her parents was fine, till i left a Poodini in the downstairs toilet..gee that was embarrassing.
When having anal intercourse with a partner, you pull out your penis and proceed to spit on your partners back, making the partner think that you have just came. Then when the partner turns around, you expel fecal matter into the partners face. (Preferably explosive diarrhea). Similar to the houdini
A Poodini occurs when you are on the toilet, for what we shall refer to as a 'number two' and you turn and look down to inspect the specimen and find it has completely vanished into the pipe - leaving no trace. Furthermore you check the wipe to find that the paper remains clean.
Almost convinced you have simply imagined the poo...you exclaim 'Poodini!'
Just been to the loo and would you credit it...a Poodini!
