A cryptic form of spoken exclamation that seems to be to no one, for no one, said out of nowhere, but is spoken for a certain party to casually overhear, and is meant to critiscize something that party had done in the past that the speaker knows well about without direct confrontation.
If you are tattled on for mocking a peer by saying of their appearance. ''They look like a monkey and a giraffe had a baby.'' Then a few days later you are with that person and you over hear them saying of something else, ''You know, I think I would say that even looks like the offspring, of say...a monkey and a giraffe.'' Leaving you in a confused state of paranoia that they had learned of your mocking them and are now telling you they know by speaking in a Knowhere.
