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.

When your son slips in the shower and instead of helping him you teabag him instead.

When you slip in the shower and your dad walks in but instead of helping you he Teabags you instead.

When your Son slips in the shower but instead of helping him up, you teabag him instead
