Padonk refers to the sound made when a heavy, meaty shit drops from ones anus and makes contact with the toilet water situated below.
The 'pa' is the sound of the initial shit-to-water impact where the 'donk' is the heavy sound of the full turd following through.
One must be cautious if they hear the 'Padonk', as it can follow with a splash of cold water into the anus or surrounding area.
Dude, your Padonk was so loud, it warned me to prepare myself for the stench that followed...
