Now imagine an object that needs to be turned 720 degrees to return to the same position. Some particles are actually like that (electrons, for example). This is designated by a spin of 1/2 (as in, one full rotation flips it around, and it needs a second full rotation to reset).

why the hell this is bringing me traumatic flashbacks of when i went in a rabbit hole learning why and how 4 dimensions rotations are used in 3d software to avoid gimbal locking

Ah, quaternions, good old fun. You can use them to describe these, too.
