This crown of thorns is perched atop my spine
He’s making a reference to Christ’s crown of thorns; a symbol of shame and mocking aggrandizement placed there by society. When he says it sits atop his neck, he might be referring to his mind; it sits at the end of his spinal chord and it serves as an object of shame for him. His pride is his source of shame, it is his tragic flaw.
