He Who Must Not Be Named, The Scottish Trope

^ Not either of those; He Who Must Not Be Named is for someone evil or just bad who shows up when you say their name, and The Scottish Trope is when bad things happen when something's named. This is for not saying the name to show anger/contempt/disgust/"I'm done with this" toward the [X] in question.
