Not “feasting”, though we certainly do that, too. “Fest” is a verb in NOLA, because you’ll be doing it pretty much every weekend, whether it’s celebrating traditional jazz, seafood, tomatoes, wine, rubber ducks, you name it, we’ll throw a festival for it.
Give us a regular word, and we’ll find a way to mangle it into incomprehensibility. Doubly so if that word is a street name.
Whether it’s “Drunk #1” and “Drunk #2” in the French Quarter or tees celebrating local pride, we’ll put just about anything on a t-shirt. And actually wear it.
