Depocatory is a term used to describe someone who continually engages in acts of asshattery, or someone who routinely demonstrates a lack of common sense or good judgement. One who is depocatory usually struggles to comprehend the basics of everyday life and has few or no friends. Should someone you care about begin to act in a depocalarious manner, a direct intervention (pronounced: smack) is crucial immediately.
"What was that for!?"
"You might know, if you weren't so goddamned depocatory!"
