Other forms: guzzled; guzzles
To guzzle is to gulp down a liquid very quickly. After running a marathon, you might be tempted to guzzle Gatorade, but it's important to sip slowly so you don't get sick.
If your brother somehow manages to drink an entire gallon of milk in two days, he guzzles it. And, if your big old car needs to be refueled several times a week, you can say it guzzles gas. Experts guess that the root of guzzle is the Old French word gosillier, which means "to go down the gullet," but also "to vomit."
