Used when referring to a female.

The proportion of tits to gut must be positively proportional.
Any girl who violates the proportionality rules below is said to have guttertits.... (An undesirable quality)

1.) If the girl is flat chested she mustn't be fat; i.e. her waist must be smaller than her breasts.

2.) If the girl is 'thick' (or large) her breasts must be larger than her belly.

Also, can be used to justify knocking around with a girl with some 'curves' provided she has some large breasts that are bigger than her waist.

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.
