Social media helped spread the popularity of a campus drink, BORG, an acronym for "blackout rage gallon."—Madison Malone Kircher
There's a misconception that BORGs might be a safer way to drink or that they're hydrating. … Folks might also be adding caffeinated beverages or caffeine to a BORG. Caffeine has the effect of masking the feelings of intoxication and other effects of alcohol.—Sarah Voorhees
And a Borg can be made to fit the consumer's taste. But the goal for many students is to get blackout drunk, and that's not healthy.—The Sun Chronicle (Attleboro, Massachusetts)
also: a jug filled with a BORG
… social media users claim that drinking from a borg can cut down on the chances of a hangover. That's simply not true … —Rick Sobey
