Matt Low of the our sister site WoW Insider and the very awesome World of Matticus blog pointed out a fairly interesting conversation going on over at PlusHeal. Apparently, the original poster had been using the phrase 'shut up' during a raid to try to quiet down people cross-chattering over voice comms, but after dealing with the upset it caused, they're looking for something new and more effective instead of 'shut up'.
Having been a group/raid leader myself, I can say in all honesty that this is absolutely one of my pet peeves; talking during instructions/pulls or loot distribution. It distracts from the important things and can cause quite a bit of confusion. On the flip side, clamping down on cross-chatter too much will make a group or raid feel less like fun with friends and more like a second job. As such, this morning we thought we'd ask you - how do you tell your group to quiet down without sounding like the guy from the Onyxia Wipe animation? (Link language NSFW) Are there any phrases or methods you've found effective to quiet a noisy group down without ruffling feathers? Or sometimes are you justified in telling people to shut it?
