That's quantum mechanical "spin". It is a QM effect which doesn't have a
macroscopic equivalent. It is called "spin" because it has the same units
of angular momentum (remember angular momentum? Something that your
precessing galaxies violate conservation of?) that actual rotation does.
However, it is quantized and only certain states of it can exist.  That's
unlike your toy top which can spin about as much or as little as you want,
and in any direction.

Before you put too much faith in the term "spin", don't forget that quarks
come in different "colors" and "flavors"...
