How do you use the :blush: emote?

I don't use any emotes for any real purpose. I hardly use any emotes at all. When I do, it's usually just because I felt my post was a bit too plain and needed a little extra at the end. Usually that means Ducky, Beanie poo, or Goggles. I've used the Elephant like 1 time before, and I don't even remember what it was for. Maybe it was just random usage.
