positron 

An elementary particle similar to an electron, except that it has a positive charge instead of a negative charge. It is an antiparticle, which is a particle that forms antimatter.
When a positron comes into contact with an electron, they annihilate each other, releasing energy.

Look, I got a jar of positrons! I think I'll open it.

No, you fool!!

(KABLOOOMM!!!!)

Posi-Troll 

This concept of a Troll generally only applies to forum boards.

Essentially it is a person who decides to Troll, but with abnormal intentions of only posting to help. Thus, they are almost complete opposites of Trolls.

This person will post anywhere in the Forum as many times as they think they need to get their opinion/point across. They tend to have 10x the post count of normal active forumers.

Most of them become Mods, well known through out the community, and are most definitely never banned.

- Xfactor56: Hey guess my post count now!!

- FireofJustice: Like dude I dunno or care.

- Xfactor56: Wellzz it's at 4042 now.

- FireofJustice: How? Was just 390 last week.

- Xfactor56: I just like posting and helping out.

- FireofJustice: W/e ur such a Posi-Troll...

- Xfactor56: ...... >.>

politroll 

A person or group of people who spend the majority of their time on the internet hopping from one journal or forum thread to a next creating a political discussion out of political and non political topics.

HL: "TG took over my "I Hate Babies" blog and turned it into a discussion about abortion"
AIS: "He's such a politroll."

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.
