(noun) is a type of very large shit, one that
you can't see in the pan.
Because of the speed and force that
large poo's vacate the rectum, they carry great momentum
and such turds are difficult
to stop, therefore, they keep going all the way through
the toilet so that
you can't see them upon peering down the loo.
Such dumps are very frustrating to a shitter
as they leave no sense of achievement, as big craps require hard work.
