Big Bang
A cosmological model for the Universe, describing an event billions of years ago that allowed for the existence of atoms and life. It is commonly misunderstood by ignorant people who think it began at a single point in space, appeared out of nowhere or was an explosion.
The Big Bang actually refers to a point in the Universe when it was extremely dense, but infinitely large. About 13.8 billion years ago, matter in the Universe was much closer together and space was mostly filled with an opaque plasma of light and electrons (the Photon Era). As a result, everything was unimaginably hot, and some scientists think that this heat led objects to move away from each other (hotter things expand).
While there may have been infinite matter, there is even more space through which objects can move apart. This allowed matter to continue moving away from other matter and, as a result of the expansion, the Universe began to cool down. Atoms were able to form and eventually stars and galaxies followed. In essence, one can say the Big Bang occurred everywhere; all matter moved away from each other in the tightly packed Universe.

Antiproton
The antimatter equivalent of a proton. It has the same mass as a proton, but opposite charge (negative).
When a proton and antiproton orbit each other, they make protonium. When an antiproton and electron orbit a helium nucleus, they make antiprotonic helium.

Antineutron
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.

Urban Dictionaming
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).

Positron
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.

Spongebob
The best anime ever, by far. It is about this sponge who works in a fast food place with his friend, Squidward.

Major Tom
A person who cannot hear you, no matter how many times you repeat their name. The term is derived from the song Space Oddity.
