Getting Medieval at 3 A.M.

So I'm at the OED online looking up "medieval" as an adjective to check its usage history (for a project), and I find this:

b. U.S. to get medieval: to use violence or extreme measures on, to become aggressive.

1994 Q. TARANTINO & R. AVARY Pulp Fiction 131, I ain't through with you by a damn sight. I'm gonna git Medieval on your ass. 1996 Rolling Stone 13 July 85/3 And with the metal-on-metal grinding and old-school synth whoops..Faust and O'Rourke really get medieval. 1999 Washington Post 9 May F1, I have no idea why we're talking about sending ground troops to Kosovo when we can send a fleet of Ford Expeditions and Lincoln Navigators over there. What's Milosevic going to throw at them--Yugos? These things will get medieval with Yugos. 2000 N.Y. Times 5 May E8/1 The teenage crowd screamed and cheered--but only when Macbeth got medieval on someone.

Maybe it's just me being up at three a.m. and all, but I find this--and the illustrative quotes--hysterical. Pulp Fiction in the OED? C'mon. But I'm happy to know that teenagers are whooping it up at a performance of Macbeth (rather, they have done in the past ten years).

Aside: sometimes I hate that I can get the OED is online. It's too easy. My beloved bought me a (used) copy of the two volume compact. I love it, and I enjoy the whole magnifying glass thing like crazy, but I tend to use it as a place to pile bills more than anything else. Pathetic.
