The Brief: Zucc or "The Zucc" is a demeaning nickname for Mark Zuckerberg.
This term is used to refer to the CEO and founder of Facebook. It is a combination of the word “succ,” which refers to performing oral sex on a man, and Zuck, an abbreviation for Zuckerberg. Zucc is used to make fun of Mark Zuckerberg – in memes joking that he is a robot or lizard – and in reference to his somewhat awkward testimony in front of U.S. Congress.
“Zucced,” pronounced like “zucked,” means that someone got screwed-over or played by Mark Zuckerberg, Facebook, or Instagram.
