Rumpkin is the name of a beer. ABV, though, isn't the only thing at play. I know if I drink a Brett beer, there's a chance I'm fighting a headache for the next 20 hours. I've had an infected homebrew knock me out (and I can handle big beers). There are a lot of unknowns to this story... let's say this beer got to 15-17 abv (top range of plausible). Did she have one pint? A couple? Is she 90 lbs? Anyway, beer that keeps on fermenting is infected. Infected beer messes people up. Sounds like a lot of hokum being said about the beer, but being rufied by a friend is a serious accusation... I tend to believe victims, but I'd want to know more before supporting that theory.
