Bursting:

Bursting is a firing technique in Counter-Strike 2 where a player shoots a short, controlled sequence of bullets instead of holding the trigger down. It is used to improve accuracy at medium range by limiting recoil buildup and keeping follow-up shots more manageable.

Bursting is commonly contrasted with tap firing and spraying. It matters because many rifles and pistols are more accurate when fired in short bursts, especially when the player is standing still or counter-strafing.
