Spectral Jackhammer 

When the protagonist dons 1980's-style wraparound sunglasses with Neon-sides and flourescent-tinted lenses and proceeds to jerk off into a ladle.

Spectral Thinking 

The opposite of dichotomous thinking. It is a term used by people who are recovering from thinking in black-and-white terms and finally start looking at things in general from a broader perspective, hence producing a ‘spectrum’ of thoughts.

“That dude finally started spectral thinking after years of believing food can either be only excellent or shit.”
