In a pick-up or organized game of football, the "Oh Shit!" Pairing is the pairing between an "Oh Shit!" Man and the unwilling wide receiver he usually covers. You can spot an "Oh Shit!" Pairing when the wide receiver gets hit by the "Oh Shit!" Man and screams "Oh Shit!" before he gets hit. After that one hit, an "Oh Shit!" Pairing is born. The unwilling wide receiver is usually afraid of being hit by the "Oh Shit!" Man, so he doesn't get open and might drop passes.

The "Oh Shit!" Man is the man that gives the usually bone-crushing hit in an "Oh Shit!" Pairing. You can spot an "Oh Shit!" by when an unwilling wide receiver gets hit by a strong defensive player.

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.
