A perfect circle that goes against the traditional norms of not having a proper "Top, Bottom, or Side" and instead live their lives upside-down. These types of circles are near impossible to discern from those who conform to the standard rules of circultry, as the only true difference exists only on a social level and not physical. These circles are frequently found flipped vertically, with their "top" touching the ground and their "bottom" aiming straight up. Similar in concept to a he/him lesbian albeit only exhibited by perfect circles rather than humans without self-awareness. In some cases the two terms may be swapped, usually in the form of sarcasm, or to poke fun at any instance of contradicting traits.

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.
