The act in which one consumes food whilst taking a dump, often because the individual is in a hurry and does not have the time to do both one at a time. Not to be confused with excrete.
"Shit I don't have time to eat this and take a dump! I need to get to class and take that exam. Guess it's time to excreat."
A person who doesn't flush the toilet after a bowel movement in hopes that someone else will stumble upon and be able to admire their work of art. Some hard-core excrebitionists have been known to go so far as to refrain from wiping in order to avoid obstructing the view.
