teamkiller 

Someone who intentionally attacks his own players in an online game.

Teamkilling in games originated by people exploiting game servers that accepted 'friendly fire'.

More recently, celebrity gaming figures like LOLMAN have utilised impact circles of weapons so as to become profficient at teamkilling, even without 'friendly fire' enabled. In games like Unreal Tournament, this works by firing a projectile in the right place, so that the force of impact makes a teammate fly so far that he loses a frag due to fall damage. This is a 'teamkill'.

Some guy is teamkilling, he must be banned.
LOLMAN, stop teamkilling!

Teamkilling 

The act of killing players on the same team in a game which allows friendly fire. Teamkilling can be intentional or accidental. If it is done intentionally, it's usually out of frustration, boredom, revenge, or to get something that person has.

It is also a form of griefing, and is looked down upon by those who play the game normally.
