SCOTUS is an abbreviation for "the Supreme Court of the United States" and is frequently used in headlines. It's also used as a noun (as in "SCOTUS should review this case"). It was initially used as an abbreviation for use in telegraph messages in the late 1800s. Similar acronyms have subsequently become popular: POTUS ("President of the United States") and FLOTUS ("First Lady of the United States").
