Wucci is the combination of "Gucci" and "Word." Both terms on their own mean "good," but when combined they become a super word meaning "awesome."
Wucci can be used in a multiplicity of settings, such as when describing a weekend, a drink, someone's personality, or just as an expression of amazing.
George, Caroline, and Freddie are pretty wucci people.
Dude! That party was so wucci!
Time for another wucci weekend? I think so.
Ready to go?
George: "This chicken is gucci"
