It's not a drink, at least not one I'm aware of, nor is it (any longer) a statistically unlikely combination of words. It turns out that not only do some octopuses posse up and hunt cooperatively with fishes, but they'll also haul off and sucker punch fish. Sometimes for being too grabby with the chow, and sometimes for no readily apparent reason. Maybe just to keep them on their...er, toes.
This is all according to a scientist who studied octopus fish-punching behavior, which must have been a fun grant to apply for.
Octopuses punch fishes. YES. OCTOPUSES. PUNCH. FISHES!!

Our new paper is out on @ESAEcology, showing that octos express this behavior during collaborative hunting with other fishes. This was probably the most fun I had writing a paper. Ever! (small 🧵)https://t.co/Vwg9BoaSUo pic.twitter.com/PIYuVXpM9t
Anyhow, it's been covered in quite a few places if you want to go read up on the topic of cephalopod fish-punching.
