If you're standing in a group of people, such as in AV, you can get attention from tons of people just by using an emote.
Type something like "/me hugs you." (no quotes) which puts [your name] hugs you. in tan in the chat log.
Basically, you can make a macro with a few lines that has a variety of emotes such as hug, slap, steals epix, etc.
The point is that everyone sees "[your name] hugs you." So everyone will think you're spamming emotes on them and will do emotes back to you.
Doesn't have any extremely good uses...but it can be fun when you're bored.
