- ERP -- Everyone has gotten their hyucks out of it over the years, but it is the OOC-in-IC a lot of admins won't touch. Even in the most good faith of uses, it's talking about people having sex or whatever, not about performing extensive in-character roleplay in the library. It is acknowledging that the world around you is roleplaying. Furthermore, it's regularly used by numbnuts to be jokingly creepy to others. Just say sex. I don't care about the poster.
- Antag -- A regular one for admins to note for saying, and so makes sense for the word filter of today. Some will protest that "well it might make sense to shorten antagonist in world", but this excuse has been heard a dozen times and does not stop admins from ruling on it as OOC-in-IC, Space Law suggesting the phrase "enemy of the corporation", though everyone just says "is bad" or "is tot" anyway. I don't care about the in-game antag token.
Flavor of the month crud like "amongus", or "amogus" should also be on the chopping block. I don't know if "ඞ" would work on my updated filter PR, but food for thought.
