a donut that doubles as the universe's favorite math show-off
means A torus is a doughnut-shaped surface or solid, formed by sweeping a circle around an axis that lies in the same plane but doesn't touch it.
from Straight from Latin torus, which meant a swelling, a bulge, a knot of muscle, or a raised cushion or couch — Romans even used it for the rounded molding at the base of a column. The word carried a sense of something rounded and protruding, which is exactly what mathematicians borrowed when they needed a name for their elegant ring. It may be distantly related to a root meaning to twist or turn, fitting for a shape born by turning a circle in space.
