Unless otherwise noted, these are just animations with no sound. I've also marked ones with several ways to get the same effect.
Typing !list emotes will give a list, but it is slightly inaccurate in that it lists some that won't work and doesn't list some that do. If you find one that's not listed, please post and I'll update this list!!
