Someone who shits with the door open or unlocked when there is a strong likelihood or intent they will be seen shitting
I hate going over to Tom's apartment. Every time I go in, I try to cover my eyes so I won't see him crapping. He's a total excrebitionist.

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.
Either Shaina is very forgetful of flushing the toilet, or she is just a big-time excrebitionist.
