An enormous tird that clogs the toilet...even when the user flushes with no paper in the bowl. Slonks are common the day after thanksgiving. Slonks usually stick half way out of the bowl. The user often feels the need to flush a Slonk right away to avoid clogs, but Slonks are so hugh it doesn't really matter. Only the Bradley 3000 toliet bowl is usually strong enough to eat up a Slonk.
I don't even think that Roto-Rooter is going to be able to get rid of that Slonk I just dropped.
A wild hybrid of an animal...something of a cross-breed between a Swamp Donkey and Muehlous that roams suburban neighborhoods scavanging garbage cans for dirty diapers and old newspapers and crapping on trees.
Call animal control...there's another DeRudder loose in the alley
