Back when the vile tendency to put /party or /emote or even /say stuff in macros was far more common, I really hated it and put together the most annoying countermeasure I could manage in four seconds.

A Cure I macro with three lines of chat in shout. At first it was about how I was about to cast Cure I, casting Cure I, and had just cast Cure I. That didn't seem to get the point across, because I still found myself being informed that the Ever-Emerald Goddess of Ill-Winds was using Provoke in 15 seconds to recast Utsesumi or maybe Regen so she could survive cutting her life into pieces by using her Last Resort.

So, consulted my inner-child and changed the text to a vivid description of the most difficult of my recent bowel movements. Something about pushing a live scorpion through a coffee stirrer. It still didn't get the point across, but a guy doing something else half-way across the zone had some very interesting input on how squatting to poop is much healthier.

The moral of this story is that you can't always fight fire with fire and you should squat when you poop.
