A clever, convenient combination of words created aboard U.S. Naval vessels by Marines, who do virtually nothing while onboard, to insult their entitled, lazy Navy counterparts who own and operate the vessels. Do not dwell on the meaning of the word "antifa" or "slut", as by themselves they do not affect the meaning of the phrase. However, when properly timed and executed this phrase will leave most befuddled in awe of what the fuck was just said.
Navy: "This hallway is secured for cleaning! Go the other way!"

Marines: "Bruh fuck your hallway, why don't you go choke on my musty dick you antifa slut!"
