A supermanifold is like a regular manifold (like the surface of a ball), but it has more than three dimensions. Instead of just having up, down, left, right, forward and back, a supermanifold will also have "higher" dimensions, like time and space-time. If you need to get from one point to another quickly, then a supermanifold might be the way to go!
