most likely a pint chugged down by a sober person wouldn’t result in Alcohol poisoning, but if a guy was already loaded it certainly would. I knew a guy in the army that almost died from alcohol poisoning doing something very like that.
A buddy of mine in the navy did that in port. He had to be carried to the ship's medical on a stretcher. He'd been in trouble with alcohol before and so this was the last straw. The navy kicked him out. Shame too. He was a good guy, just drank too much and the navy isn't tolerating this stuff anymore like they used to.
