The act of pausing, or "standbying" the connection in an online game, primarily on Halo2. When standbying, the host of the game (the player that the other players are connected to) causes all of the other plays to lag into a Blue screen which is the "Connecting to Game" screen. The host, however, gain a few more seconds of Game-time before he himself is also put into blue screen. Expert standbyers are able to kill every person on the opposing team without ever going to Bluescreen.
There are different types of Standby, Normal standby, in which just one player does it, and Team standby, in which the entire team (or multiple people on that team) bridged their connections together and are both standbying which is also a lot more effective and a lot harder to lag out of.
Standby is done primarily in two fashions:
1) Pushing the "Standby" button your modem.
2) Unplugging your Ethernet cord out of your modem.
However, some more intelligent people find easier ways of doing this, one being UDP Packet Flooding (My favorite).
Although Standbying is cheating, some people standby only when they are being modded. Standby causes all of the modder's abilities (super speed/jump/auto aim) to stop briefly, usually within enough time to kill him.
Standbying ends then the host either lags out of the game (and you see a "Re-establishing Connection" screen), or when the host pushes the Standby button again/plugs his ethernet back in.
Only hosts can standby.
