A dialogue bubble in a comic strip that serves less as a medium for conversation or character development and more for the purposes of explaining to the reader what they are to find amusing. It is similar to the idea of "telegraphing" a joke; however, instead of simply making it obvious that the joke is imminent, a buckleybox analyzes the joke itself in order to inform the reader from where the humor is intended to be derived.

It is often associated with a lack of writing aptitude, in that the writer is unable to artfully craft humor and must, instead, resort to prolonging the punchline to the extent that it is lost in text. In every situation of a buckleybox, it is possible to remove the box entirely while simultaneously improving the quality of the humor.

A phrase to describe someone who is cognitively degenerating. Synonym of "going off the deep end". Can have varying degrees of severity.

Reference to the song "Hey You" by Pink Floyd. The line "and the worms ate into his brain" makes no sense in an otherwise linear and literal narration throughout the lyrics.
