It's fun, if someone lies on messenger you can just put a cap emoji on their message instead of calling them a liar. Time saver. Dare I say we need such an emoji response here?
My best guess as to what happened here is this person said "I want a tattoo of Samuel L. Jackson cosplaying as Wednesday Addams. No, wait, I want Gollum as Wednesday. Can you do both? Like, if Jackson and Gollum had a daughter made in a lab from combining their DNA, and their daughter cosplayed as Wednesday Addams?"
