“SCROTUS” is an acronym for the “Supreme Court Of The United States.” The term was used by 19th century telegraphers and appears in the book The Phillips Telegraphic Code (1879) by Walter Polk Phillips.
 
The slang term “SCROTUS” (Supreme Court Republicans Of The United States) has been used to label the Supreme Court’s conservative justices.

The telegraphic work in the newspaper offices is a supreme test of the staying powers of an operator, and few women are equal to its requirements.
(...)
The use of the machine has led to the formation of a special code. For instance, the operator receiving over the wire the word “scotus” has to write out on his machine “the Supreme Court of the United States.”

To illustrate: S-c-o-t-u-s stands for the “Supreme Court of the United States,” a sign obviously made from the initials of the words represented, just as “potus,” makes “President of the United States.” While Scotus thus stands for six words, it is impossible to have “s.c.,” its first two letters, stand alone for “Supreme Court,” because those letters are wanted for South Carolina. “Supreme Court” by itself is not abbreviated.

In English, the first known acronyms (as opposed to plain old initialisms) cropped up in the telegraphic code developed by Walter P. Phillips for the United Press Association in 1879. The code abbreviated “Supreme Court of the United States” as SCOTUS and “President of the…” as POT, giving way to POTUS by 1895. Those shorthand labels have lingered in journalistic and diplomatic circles—now joined by FLOTUS, which of course stands for “First Lady of the United States.”
