I'll start with one that doesn't seem directly related but correlates so closely that I can't help seeing the "tell" as a warning: putting "kappa" in a sentence like a punctuation mark. I've never seen an online conversation that started with that tell and didn't wander into final solutions and 14 words if it went on long enough. I know it's a :freeze-gamer: thing but it's not like there isn't already a wide overlap between :freeze-gamer: and :frothingfash: .
