paintard
A person who hauls an entire can of paint up a ladder like it's their life, then trips on nothing and dumps the whole mess over the door, wall, and sidewalk.
I saw my cousin drop a gallon of blue paint on the front steps. Now the neighbors think we’re having a tantrum.
He tried to look cool while climbing the ladder, but then he slipped and painted the street like a kid with a crayon.
My dad did this last weekend. He turned our porch into a rainbow disaster.
