What is this?!

M • Boy mama x4 💙💙💙💙, Expecting #5🩵

If this is truly nationwide, are any of you other mamas receiving emails like this? Are you keeping your children home as a precaution or do you think that it’s rash considering this is supposedly a vague threat and could mean nothing? My husband wants to keep the kids home tomorrow. I could see that if this was a local thing, but I have no idea what this is even referencing as I don’t do tiktok. Anyone have more insight?!
