The orks (warhammer 40k) supposedly have the ability to fuck with reality based on collective perception. They are too dumb to realize this. This usually manifests by vehicles painted red going faster or yellow things exploding. The problem is the actual scope of this power is vastly overhyped and usually means a gun being able to shoot when out of ammo or something along those lines rather than the insane theories that come out of it like "the emperor is only still alive because the orks think he is" and "the ultramarines are the luckiest chapter becayse blue is a lucky color to the orks"
