To surprisingly poke an individual while scaring them. To achieve this you must run on the balls of your feet toward the individual while they are occupied with another activity or while they are just not paying attention. But be sure to run on the balls of your feet, as so they can't hear you coming towards them. When you get close enough (while still running) you poke them, HARD! And then run away laughing, because the individual will look hilarious afterwards. They will look like somewhere between the mix of having a heart-attack and surprize and pain.

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.
