Top Definition
A particle emitted by an incredibly fat person, the first, and as yet only, recorded case being Tom. A Tomatron is the densest particle in existance, so dense that just one is capable of bending light and eight of them can block a black hole. Also has the side efect of draining the intelligence of people nearby.
Han Solo and the Millenium Falcon were on the verge of falling into a black hole until they kicked Tom out of the airlock so that he could block it with his Tomatrons
