Because it looks a bit like a [turtle](https://en.wikipedia.org/wiki/Maryland_Terrapins)? My wife was/is a Terp. Obviously not an answer.

[Terp is a Frisan](https://en.wiktionary.org/wiki/terp#West_Frisian) and Dutch word meaning a low artificial hill for shelter during a high tide. See [Wikipedia](https://en.wikipedia.org/wiki/Terp). Before dykes were built, farmstead were built on *terpen* to protect them from the frequent floods.

This is super because it is so much bigger than the small *terpen* that Frisian farmers would make to be safe from floods.
