Regina Phalange is the fake name Phoebe Buffay uses in Friends when she needs a quick cover identity, and it became one of the sitcom's most quoted running jokes. Because the name sounds official yet absurd, fans began repeating it whenever they wanted a playful alias, and short clips of Phoebe saying it spread through reaction videos, edits and soundboards. It remains popular because it instantly signals a secret identity without any explanation, making it an easy punchline for Friends fans and for viewers who know the reference only from memes.
