When you talk the talk but can't walk the walk. This guy thinks he's a Shooter but is only a dribbler. A suburban outdoorsman who couldn't catch a 5lb bass with bucket full of worms. Likes to dwell in garages while smoking bogues with like minded individuals.

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.
