Predator's beer funnel
Or Sub Zero's, I guess, as the method of delivery for a triumphant libation after a particularly brutal Mortal Kombat style fatality. Take your pick of any spine ripper. It's only $13.99, but it is a little late to order it for your Halloween party tonight, so instead, we will open up this post's comments to field this hypothetical question: which liquor most resembling spinal fluid would you chug out of this thing? Please justify your answer.

You can pick these up at any local "Spirit" Halloween Shop.
Whether or not it has lead based paint is another question entirely.
Also be classy use a red wine...
Great for ritual blood (or wine) sharing.
Except spinal fluid is mostly clear, so using it for wine, cinnamon schnaps, or other blood-like liquids would be inaccurate.
And who want's to be inaccurate when drinking alcohol from a plastic skull-and-spine-shaped beer bong?
My drink of choice would be a Mojito. But a freshly made one, not one using a green mix. It should just have a pale yellow-green cloudiness to it.
Plus, everyone knows that spinal fluid tastes like lime and mint.
Here's a video from my podcast where we put that thing to use:

BTW- we named him "Gregory Spines".
Killian's Red, of course. Yummy red beer.
Bonging red wine (or stronger stuff) is way out of spec for Human R1. Projectile style rejection - trust me on this - you don't want to see it.
I have bought a couple of these over the years. my fiancee used to work in a costume shop, so she'd bring one home to me every once and a while. of the 3 that i've owned, only one was free of holes enough to actually drink out of.
I think the appropriate drink is the suffering bastard.
Jazzbo, sounds like there's a lovely story there. Probably one best left unshared.
I think tequila, yellow - not white, would be most appropriate to be drinking from a skeleton. It would have the appropriate sickly color and noxious smell and taste of diseased spinal fluid. Although Absinthe with water to make it cloudy and diseased-looking would also work; sort of a gangrene meets meningitis concoction. MMMM, yummy.
Friesengeist! Or, Moorgeist. Either way, light the surface on fire and let 'er rip. Oh, be sure to dial 911 just before go time.
I first encountered one of these at a strip-mall nearly a decade ago and at the time could not help but see it as emblematic of the permanent union betwixt goth and trailer-trash.
Ah the only way that Pabst Blue Ribbon can be drank. As it tastes terrible no matter which direction it's going.
Somewhere there's a beer bong shaped like a cock and balls.
Local Spencers stores should have these, saw one in mine a day ago.
I think the bum wine Cisco would be the best fluid for this item. Preferrably the "Berry" flavor.
