A corkscrew landing (also spiral landing) is a method of penetration that is intended to minimize the risk of the man being hit by anti-aircraft fire from the ground on his way to the destination orifice. Instead of slow descent towards the hole, in a corkscrew landing the phallus is positioned at high altitude above the entry port, then descends rapidly in a spiral. The manoeuvre is typically performed by pilots of military aircraft.

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.
