Definition

A family-friendly pun for describing volcanoes that have historically ruined everyone's day by spewing volcanic ash everywhere. It's geology humor for people who appreciate a good wordplay while discussing pyroclastic flows. Basically, Mother Nature's way of being a jerk to entire civilizations.

Example Usage

"Mount Vesuvius was a real ash-hole back in 79 AD, burying Pompeii under volcanic debris."
