Describing the teens at Forte Junior High, they're all headasses who always have to make drama and be jerks to people they don't even know or talk to. When someone complains about them, they immediately are insulted. When they could just stick to what they consider themselves, as people who "don't give a shit about what others think of them".
They also tend to care more about their football games, then just teaching school. Even the teachers are barely teaching, instead they let the students interrupt them with "Are you going to the game, Ms. ****!?"
And honestly, most of the 8th graders are the only realest kids. When the 7th graders think they're much better, they're worse. Most of the 8th graders there are super genuine and cool.

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.
