When playing to much guitar hero and you seem to notice the tv getting stretched out and the walls moving uncontrollably.

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.

desribes when you've played guitar hero soooo long that when you finailly peal your eyes away from the screen everything is wavy and moving, like your high.
