Squircle
A squircle is a shape intermediate between a square and a circle. There are at least two definitions of "squircle" in use, one based on the superellipse, the other arising from work in optics. The word "squircle" is a portmanteau of the words "square" and "circle". Squircles have been applied in design and optics.

Why have I never heard of a Sphube before? This is outrageous.

I have an entire SageMath Jupyter Notebook devoted to Squiganometry. That is some fun stuff to play with!
Matt Parker has a great episode on his channel dedicated to the Squircle.
