A schmalaxy is a heavenly body that orbits a galaxy yet does not qualify as a galaxy. Examples of our Milky Way Schmalaxies are: Canis Major Dwarf, Large Magellanic Cloud, Booted Dwarf, Virgo Stellar Stream, and Omega Centauri. You can think of them as being moons of a galaxy.
One of our nearest foreign Schmalaxies is Andromeda II which is gravitationally bound to Andromeda. The neat thing about this alien non-Milkian Schmalaxy is that it is closer to us than our own Leo A Schmalaxy.
