This is the thought version of Speak in Unison- when multiple characters are thinking the exact thing at the same time. This generally happens when the thought they have in common is the first thought that would naturally come to mind in that situation; for example, when a character makes a Captain Obvious remark, all the listeners will think that they knew that already.
It's usually played for comedy to show that two or more characters think the same thing, whether because they're on the same page or the thought is that obvious.
Compare Strange Minds Think Alike, in which two(or more) characters come to the same improbable conclusion. Also compare Finishing Each Other's Sentences, Shared Dream (in which two people literally have the same thoughts when they sleep) Twin Banter (the tendency for twins to speak in unison and finish each other's sentences), and Twin Telepathy (the Maybe Magic, Maybe Mundane tendency for twins to know what the other is thinking).
