Definition & Meaning of "two-four"in English

What does "two-four" mean in Canadian slang?

It is used in Canada to refer to a case containing 24 bottles or cans of beer, a common party or gathering size. People typically say "Grab a two-four for the cottage" or "We crushed a two-four last night." The term originated in Canadian beer drinking culture, likely in the mid 20th century, as 24 packs became a standard retail size, and remains a widely understood and proudly Canadian term, distinct from American "case" or "30 rack."
