NCIS fans. What does Simafri mean?!

Question:

NCIS fans. What does Simafri mean?

---

In the show there is mention of Simafri or Simafry ... not sure. Its a brilliant show but if you miss this little thing some instances of Military talk are completely miss-interpreted.
HELP.

Answers: Agent Gibbs sometimes says,

????semper fi

which is short for:

????semper fidelis

which is latin for

????Always faithful

and is the motto for the US Marine Corp.

See the reference below. Source(s):
http://en.wikipedia.org/wiki/semper_fide... What was the context or scene where it was used? It could be an acronym for something. It could be military-ese, forensics, general criminal investigation speak, or since this episode involved arms dealers and the CIA, it could be related to those fields.
