I was playing a game and being supportive. Every round we won or lost, i would go "Nc team" or "nt nt". When the game ended, one of my teammates said in all chat: fl this viper

I tried searching it up on google and the only results were "fake laugh", "floruit" or some other word that doesn't make any sense with the sentence.

Unless the teammate is trying to mock me by saying "fake laugh this viper", i don't know what to think.
