Death Lag 

When your character is killed in the middle of something resulting from a horrible lag. The player's character could either be killed by an enemy player, the game environment, a NPC or some monster in the game. As long as the game connects via internet, then this could happen as long as that connection is bad or "laggy".

This mainly occurs in overpopulated MMORPGs or games with otherwise bad internet connections that occur frequently, eg. RuneScape and Call of Duty 4.

Player 1: "WTF happend?! We were just about to win!"
Player 2: "Damn noob killed me because I lagged."
Player 3: "Dude, you were just owned by a 'death lag'!"

Great Lag Spike of Death 

This death occurs exclusively in the world of online multiplayer computer games, namely Garrys Mod. This is experienced only on online servers with a lot of addons, players, and ping. This causes the entire server to freeze up, and time out many players, and crash the remaining. This is awfully similar with the recent DDoS strikes on other multiplayer games.

I tried to play Teh Build Box on Garrys Mod but we experienced The Great Lag Spike of Death.
