What Does SU Mean?

SU means "Shut Up". The abbreviation SU cannot always be taken literally. In other words, it is not always used as a blunt way to tell someone to stop talking. In recent times, SU is more commonly used as an exclamation similar to OMG (Oh My God!) to express disbelief. For example:
  • Janet: John asked me out on Saturday.
  • Sarah: SU!
  • (Here, SU means "No way" or "Oh My God".)
