To be storm trooped is to be made all white with black details. This comes from the imperial soldiers in Star Wars who were of the same colorway. This is most often used to describe clothes or cars.
Kid 1- Yo did you see Rob Dyrdek's Tahoe? It's fucking badass with the solid white paint with black tint and black rims. Even the Chevy symbol is blacked out.

"Holy crap, I was storm trooped hard last night."
