An orgy activity in which several men lay naked next to each other while another person strokes their penises, one stroke at a time, going along the row of men, repeating as necessary until each man has ejaculated. It is named for its similarity in nature to the tale of Santa Claus, who enters homes through their chimneys to deliver presents and then quickly leaves, with the penises representing the chimneys and the hand representing Santa. Can also be done as a competition to see which man can last the longest.

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.
