To explosively pound out a liquified dump, typically in to a toilet but not exclusively, that
sprays uncontrollably all over the
sidewalls of the bowl and your own ass. Due to it's uncontrollability and power, many people have
spackled there pants, own legs and anything in a 4' radius just short of sitting down. It often resembles what pudding being fired out of a shotgun would look like.
I drank 20 budweisers last night and went on to spackle not only my
undies but
the toilet bowl, seat, my legs, shoes and
bathroom floor.
