What is a feeder in league of legends?

Answer 1

A feeder is a player who constantly dies by an enemy (either on purpose or an unskilled player) which greatly disadvantages your team, because your enemy can gain more gold and therefore they can buy stronger items a lot faster, which will then be harder to kill them. In order to avoid getting killed by a fed player is to never fight against 1vs1, unless in a team fight and aim them first because your team can catch up to its level while the player is in waiting time.
