Marfed is when your cat throws up a not completely dead mouse or similar small animal.
Nug was on the couch wheezing and then he Marfed . The mouse , a little stunned woke up and scattered.

An acronym, short for "Modifications and Additions to Reactor Facilities." It is the name of a prototype reactor plant run by the U.S. Navy and the Department of Energy, located in upstate New York. It is a disastrous cluster-fuck of a Destroyer's engine room (surface ship's steam plant) and a S5W/S7G primary plant (fast-attack submarine's reactor plant), which results in nothing making any sense at all, and everything breaking constantly. According to a rumor I just heard, a large primary-to-secondary leak recently occurred and the plant is going to be shut down forever.

Also means, "Make another round, fucker!" and is said to someone who's sitting around, on watch, not using their time the way they're supposed to (bullshitting, not paying attention to equipment/machinery).
Person A: What plant are you in? S8G?
Person B: MARF :(
Person A: *shivers* I'm sorry man.

A small amount of regurgitated stomach contents (barf), that is not thrown up with much force. The contents only make it as far as your mouth. The "m" for mouth is substituted for the "b" in barf, hence marf. Usually you don't know it's coming and it is commonly simultaneous with a burp or hiccup. Can be used as a verb or a noun.
Neal: Uhhh, i just barfed in my mouth.
Peter: Ya, marf tastes pretty fucking gross.
