what should the punishment be for saying "Lets Go Brandon"?
Are we still talking about dress codes here, or just words? The general punishment for wearing clothes that don't fit the dress code would be having to change. Maybe if it's a regular problem adding more teeth to it.
I can remember my middle school banning Fudpucker's shirts, even though that's a real restaurant in Florida (?) because everyone knew that it was a substitute for the F-word and was wearing them to be edgy.
Is it the same for saying "frigging" or "mother trucker"? What about "shucks" or "dern"?
Whether we're talking about shirts or just saying the words, I would assume we'd treat it the same as if the shirt or just a person said the word they're substituting, assuming they knew that it meant that. (For example, I never knew shucks was a substitute for ... sh**t?)
I can remember a teacher in 9th grade busting a classmate for saying "effing" and telling him to watch his language from now on or she'd send him to an assistant principal. He complied.
