Six-Pack

Reader's Digest Feb, 2017の記事 'In Case of Blizzard, Do Nothing' から引用します。
In the winter of 1985, my hometown, Buffalo, was engulfed in a blizzard--not an uncommon occurrence for the region, which is justly famed for epic snows. But this was a big one, and the city's blustery Irish American mayor, Jimmy Griffin, was at pains to persuade people to stop trying to go about their business as conditions deteriorated. He urged Buffalonians to "relax, stay inside, and grab a six-pack," which must be the best advice any elected official ever gave the public in an emergency situation.
"six-pack" と言うと "abs" ("A set of well-developed abdominal muscles." [as modifier] 'six-pack abs') を直ぐに連想しますが、ここでは明らかに別物です。ここでは次の意味ですね。
・Macmillan Dictionary:　six bottles or cans (=metal containers) of a drink that are sold together; a six-pack of beer
