It is simply the study of pits. Of course, a pitlologist must pick a field to specialize in (e.g., watermelon pits, BBQ pits, or the study of pitiful situations and puns).
When I grow up I want to study pitology since I'm so good at falling into them. I'm going to study pits in the Amazon, Aztec ruins, ancient Buddhist temples, and various tombs in Egypt and India.
