OK, we all know that USMC stands for the honorable "United States Marine Corps" and some people refer to them as "Uncle Sam's Misguided Children". However, in early 1987 there was a big scandal where one or two security guards at the U.S. embassy in Moscow, U.S.S.R. were caught being involved in an espionage ring and security breach, and one or more of the guards (who were United States Marines) were in a sexual relationship with a Russian female agent. They were court-martialed and for a while "USMC" was an abbreviation for "Under Seduction of Moscow's Cunt". This occured even while Reagan and Gorbechev were in a state of friendly dialog and Cold War tensions were lessening.
This USMC/embassy mess did not stop the talks between the U.S.A. and the U.S.S.R. from continuing. The Cold War ended peacefully a few years later and the incident was largely forgotten.

Acronym denoting the United States Marine Corps. Also jokingly defined as 'Uncle Sam's Misguided Children' in reference to it's counter-cultural characteristics. To many members it's also defied as 'Uncomplicated Shit Made Complicated' referring to the Corps' ability to turn any simple task into a complex, micro-managed mess.
Civilian: so why can't you just ask to use the bathroom during a brief?
Marine: I don't know dude. USMC. It's what we do.
