But Q told us what the first boom was. The word was used in a tweet about an oil boom in the USA and then Q asked us if we noticed the boom.
I think these booms will all be like that. The word boom will be used in a tweet or a headline from someone like Sara Carter. They may be about the boom on a sailboat sweeping the decks clear as a metaphor for firing a bunch of criminals in government positions. Or something else.
But not explosions. And it will be nothing that can be predicted that is not already known. It will not warn anyone to run from the boom.
