The Baader-Meinhof Phenomenon is the phenomenon where one happens upon some obscure piece of information???????? often an unfamiliar word or name???????? and soon afterwards encounters the same subject again, often repeatedly. Anytime the phrase “That’s so weird, I just heard about that the other day” would be appropriate, the utterer is hip-deep in Baader-Meinhof.
That’ll explain why you’ll hear a lot about Scandinavian death metal in the next few weeks.
