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.
It is a state of being, blowingcoke and laying in your pajamas all day skipping class, then wearing those same pajamas to a party that night, while doing all of this you never lie, joke, or kid about things happening in your life
You are being a waste of life cokehead, stop being a "Spackle "
