An Obedience Cage is a cage that can be locked big enough for a human, commonly a commercially available pet cage.

Within BDSM it is used by Dominants as both the home for and punishment of the Submissive.

E.g. In a Male Dominant Master / female submissive scenario:
- The Master would promote the Obedience Cage as the female submissive own domain, where she could go voluntarily when not required by her Master (in which case she would not be locked in and free to come and go withing the greater domain confines) or as a place of punishment (in which case she would be locked in).

- The Obedience Cage is often at the side of and gives direct access to the Master’s bed, the submissive being required to sleep in the cage and locked in a night.

- The Obedience Cage is also used for the purposed of denial and to ensure that a submissive is forced to watch / hear her master entertaining other females in his bed.

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.
