TF2: t pose pyro
just a little glitch.
Here's how to do it:
1. Drop your flamethrower by killing yourself (not literally)
2. Airblast until the ammo you have is the last airblast.
3. Use up the remaining ammo by flaming, hold Mouse 1 and don't release.
4. When you have used up the ammo, do not let go of Mouse 1 and pick up your flamethrower from your previous life and you're done.
