Joust  

ZAM Network Wikibase™ Dictionary

Jousting is a raid maneuver that has all or most of the raid force moving back out of AE range just before the AE goes off, then moving back into melee range until the next AE. This has the advantage of reducing damage on those outside the Main Tank group.

To make this a successful strategy, one player needs to be responsible for calling the joust with "All in!" and "Everybody out!". In all likelihood, this player will need to be using a parsing tool like ACT or other similar application with timers.
