How to choose a reaction gif:
1. Type a couple words relevant to the topic or your feelings on the topic into a gif search engine.
2. Pick whichever gif suits the context best.
3. Watch as everyone thinks you're super clever.

I mean, I get it. Most people just want funny pictures, and I love sharing memes with friends. But something about reaction gifs just boils my blood. I'm very, very bothered by them. If someone posts a relevant comment, or video: great. If there's something really clever about the reaction gif: good job. But most of the time it's just kind of related, and not really a discussion at all. Or worst of all, a "wow" "lol" or "wtf" expressing funny face.
