Edge Guard Edit Meaning

1.

A term that is often used while playing fighting games, especially Super Smash Brothers Melee. One who edge guards stands at the edge of the platform and continuously smashes the opponent off of the edge. Eventually, the opponent will no longer be able to make it back onto the platform, which will result in his or her death.

Marth, you fucking cheap son of a bitch! Why don't you go somewhere else and stop edge guarding!
