AKA the POP Filter
The POP filter in came about after playing many sessions of online D&D, and observing how many players would talk on top of one another, interrupt their fellow players and the DM, and break up game flow unnecessarily. It is not intended to make it so your character doesn’t get to do anything cool or fun, rather it is a support so that everyone at the table to gets a chance to do something cool, heroic, and fun.
The POP filter is built around a mechanic called Chiming-In. A Chime-in is a vocal cue that signals to the DM that a player wants to do something. Chime-ins allow players to do this without interrupting the flow of the game, steal another player’s moment in the spotlight, or break the DM’s mental bandwidth. A Chime-in can be used for anything you may want to do in the game, from asking the GM a question, to having your character check for traps, to sneaking through the enemy’s camp in the dark of night. The sky is the limit.
