A cuda (used "y'cuda" when calling someone one) is someone who mindlessly and instinctively follows trends, regardless of how dumb the trends are. This kind of behavior is both incredibly irritating and prevalent in 2017 culture.
The word stems from an analogy made by Chris D'Elia on his podcast Congratulations where he compares people who go to events like Coachella as being like Barracuda's, fish that just blindly follow the crowd.
Oh, you go to Burning Man and camp out for a week in the middle of the desert and dress like a fairy? Y'cuda and frankly, y'lost...S'whatyare.
