The word "boogaloo" has been in common (well, sorta common) usage as a humorous shorthand for "when the current cold civil war goes hot" for a while now. But that isn't the same as groups using it in their name, and that in turn isn't the same as there existing a "boogaloo movement".

And that doesn't mean that there aren't groups that have been around for a long time with philosophies that some might now categorize under that term.

Unless a person or group attaches a label to themselves, and explains what it means to them and why they use that label, it is a fault of logic to accept any label uncritically.
