What does aggro ceiling mean?

aggro ceiling meaning in Urban Dictionary

whenever a raid supervisor in an MMORPG (such as wow or EverQuest) features an ability that reduces the tank's aggro by a hard and fast percentage. Since a tank is only able to establish a lot of aggro in a set time period, and because the employer performs this aggro-reducing capability periodically, there will be a maximum number of aggro a tank can create.In WoW, this first seems on Broodlord Lashlayer in Blackwing Lair, since earlier aggro-reducing employers minimize a set amount of aggro, without a portion. In addition it seems from the three drakes, Firemaw, Ebonroc, and Flamegor.Other players (form tank) must be careful to manage their aggro on aggro roof battles so as not to pull aggro, being that they are not struck with all the aggro-reducing capability.
