A variation of the term Safety Pilot in aviation. A term not spoken but implied by arrogant pilots who want a one-sided arrangement without switching roles or paying for the other person's $100 hamburger. Usually stated as a command (i.e. "You can be my Safety Pilot!") instead of asking nicely or offering a quid pro quo arrangement.

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.
