After doing some digging around, it seems that the phrase 'Everyone Dies™' isn't actually trademarked. I couldn't find any official records or databases indicating that this phrase is protected by trademark laws. It appears that people may use '™' symbol informally to add emphasis or a comedic element, but it doesn't necessarily mean legal ownership. So, no worries, you're not going to get sued for saying 'Everyone Dies™'. It's just a phrase, not a legal minefield.
