K-Bar 

K-Bar also given as Kbar, Ka-Bar or KA-BAR is the name of a combat and utility knife adopted during World War II by the United States Marine Corps as the 1219C2 combat Knife. Later redesignated as USMC Mark 2 Combat Knife, the knife was also adopted by the US Navy as the US Navy Utility Knife, Mark 2. Besides being the name of the knife, k-bar can also be used as a verb, so if you k-bar someone, you kill them with a k-bar knife and someone killed in this way can be described as having been k-barred.

“I am pissed off with the bullshit we’re getting from that new STRAC REMF LT. As soon as we get out into the boonies, I’m goin’ to K-bar the bastard.”
