When one buys Cajun Fries from Five Guys with the intent of emptying the fries from their cup, and replacing them with Coke, thus receiving a free beverage (granted, the coke is added to a cup still filled with the Cajun Fries' crumbs)
Pierre: "Bro, lemme see the cup in your Five Guys Cajun Fries bag."

Kane: "Why dude, what do you want it for?"

Pierre: "I'm thirsty, imma use it to get a Cajun Coke."

Kane: "Damn dude, that's genius."
