Not being a team player. A selfish act where what you're doing is helping (ie: feeding) yourself or the enemy, either on purpose or by being a noob, sacrificing the entire teams potential.

A term in team-based video games used to describe someone who is not playing with the team and/or is playing selfishly. This person will usually stray away from the team/objective in a match. The enemy team will be able to take advantage of this situation by either being able to kill the "feeder", or pushing towards the objective while the "feeder" is unable to help. The word originates from games where special abilities can be obtained through dealing damage. If a person is getting damage dealt to them constantly, they are "feeding" the enemies ultimate.
