When you think you're tough or have a lot of backup or connections. Similar to a keyboard warrior. Talking the talk but can't walk the walk. Thinking you are tougher than you actually are when in fact you hide behind a phone call, text message or keyboard. Also similar to a bully. Trying to seem threatening when truly you ain't shit. More often than not the one trying to pull heavy is the one in the wrong but too embarrassed to admit it and pulling heavy is their defense to try and ward off their stupidity and nonsense that they themselves created.

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.
