If you're like me, this is a brand new mathematical term. It's actually a pretty cool shape that comes in a few different forms:

MammothMemory gives us a good explanation for how a frustrum is formed: A frustum is the shape you are left with if you cut the top part (the pointy bit) of a cone or pyramid off parallel to its base.

Take the tops off a cone and a pyramid to get a Frustum

WolframAlpha gives two more technical definitions of the two different types of frustums:

A pyramidal frustum is a frustum made by chopping the top off a pyramid. It is a special case of a prismatoid.

A conical frustum is a frustum created by slicing the top off a cone (with the cut made parallel to the base).

Here are some frustums you might see in your day-to-day life:

The Snake consists of 24 isosceles triangular prisms, connected by spring bolts. The prisms can't be separated, but they can be twisted, allowing one to form the snake into many different shapes.
