I've been so pyro ever since that car was parked outside my house for hours.

I smoked way to much and now I'm feeling pyro. I don't wanna be here.

The best "fuck people over" class in Team Fortress 2. The Pyro is good for fucking people over, mainly characters like The Spy, because he can pretty much blast fire everywhere in a room and end up killing every cloaked Spy inside. One cannot tell what the Pyro is saying behind his mask, whenever he tries to talk all you hear is a bunch of "hmmhmhhhmmm". The Pyro comes fully equipped with a Flamethrower which can continue to do damage even after death, and an axe known as the "Axe-tinguisher" the Axe-tinguisher is an axe wrapped in... barbed wire... and has a 100% critical chance if the enemy is on fire.
The Pyro: HMMMHMHMH

A slang for a pyrotechnician, usually used to describe anyone who likes fire, or claims such. Many associate them with anarchy, because of the anarchists cook book, a work that is hated by almost all professional pyrotechnicians. Due to mis-understanding by the general public, pyrotechnics as a hobby is getting harder and harder to really get into.
The true art of pyro is slowly dying.

A "pyro" is a person addicted to fire. Most of society (mainly teenagers) claim to be pyros, just because they like to play with fire. In fact,

"pyro" is short for pyromania, and it is a mental addiction to fire. For a pyromaniac, it's not normal to go a day without fire. They usually handle themselves well normally, but when around fire they could become jittery, aggressive, and obsessive compulsive. They can be obsessed with exploding things, may carry lighters at all times, and may have mental disorders such as Schizophrenia and Psychopathy. If someone is a "pyro" it is extremely noticeable.
Pyro: Dude, this morning I made 3 drano-bombs, and lit them all off at the same time. It was awesome! I also added another 2 lighters to my collection. Want to come over later? I think I'm going to make some more bombs. I hope the bomb squad doesn't catch me this time. Later me and some friends might go light this guys house on fire too!
