When someone adds their own (or another person's) name to Urban Dictionary, either to flatter said person or to insult them. Urban Dictionamers don't realize that no one will read or care about these definitions. In the end, this is just extremely irritating and fills up the voting list (although I doubt the site's moderators will care enough to stop it).

The antimatter equivalent of an electron. It has the same mass as an electron, but opposite charge (positive). Both electrons and positrons are created by photons through a process called pair production. Positrons are sometimes called "antielectrons".
When a positron and electron orbit one another, they make positronium before annihilating shortly after. A positronium atom can bond with hydrogen to make positronium hydride, or with another positronium atom to make di-positronium.

The antimatter equivalent of a neutron. Just like neutrons, antineutrons have no charge. However, antineutrons are made of antiquarks, which have the opposite charges of a neutron's quarks; as such, neutrons and antineutrons will annihilate upon contact.
