Minecraft wiki entry for Player_versus_Player, associated text: Many competitive PvPers can click fast, to increase the number of times they hit a player. Some methods of fast clicking include Jitter Clicking, Butterfly Clicking, and Drag Clicking. Click speed is measured in Clicks Per Second (CPS). Most PvPers are able to Jitter Click about 8-16 CPS. Depending on the server's hit delay (10 ticks by default) you will be able to hit an opponent more times within a second. Note: Butterfly and Drag clicking may not be allowed on some servers. Java Edition added a weapon cooldown in 1.9, however, it is still possible in Bedrock Edition.
