If I were still in the classroom I would just go along with the trend. It's no different than when "21" was the latest trend. I taught band and orchestra so every time I said start at measure 21 the kids would say,"21" like the little boy in the viral video. I started saying it with them and we laughed and moved on.
Detention would be overkill unless it was truly interrupting the educational learning time of the rest of the class.
Assigning an extra writing assignment for a discipline issue should never be done. It just makes children hate writing. Much like making a child do pushups as punishment.
Restricting/excluding students from fun activities should be a last resort. Just as I said for the detention, if this is truly interrupting the learning time for others then maybe this should be a step. This would be after a hallway conversation, phone call home, then a detention. If this didn't solve the issue, then a possible office referral for further discipline. But this should only be used if it is extreme.
Teachers know that if you use the trend as well it's cringe and the students no longer find it fun.
