Purim
The Purim festival is officially named after “lots”, but is celebrated by dressing in costumes & masks. It also celebrates Esther, which puns with “veiling” & “hiding”. So the real meaning must have something to do with masks, costumes, veiling, hiding. I suggest it is עפר ˁpr, which means “cloaking” & “covering”.
Hebrew, Aramaic ˁpr = covering, cloaking
Needless to say, there’s nothing wrong with common folks celebrating Purim. It’s just a joke by the spooks.
