What does beefed mean?
"Beefed" is the past tense and past participle of the verb "beef," which carries two distinct informal meanings. Its most common modern use appears in the phrase "beefed up," meaning strengthened, reinforced, or expanded — a city might have beefed up its police presence, or a company beefed up its software before launch. The older sense means complained or grumbled, chiefly in American slang, as in "she beefed about the noise." The noun "beef" in this figurative sense dates back several centuries, and the verb followed. The strengthening sense likely draws on the idea of adding muscle or substance, much like adding beef to a meal. Both senses are casual rather than formal, so they suit conversation and journalism better than academic writing. The word is vivid and widely understood, making it useful when a plain term like "increased" or "complained" feels flat.

A word for meat became a word for complaining — likely because grumbling cattle once got a bad reputation as quarrelsome beasts.

Etymology of beefed
The word traces to Old French "buef" (modern "boeuf"), from Latin "bos" or "bovem," meaning ox or cow, entering English in the Middle Ages as the name of the meat. By the seventeenth century "beef" had developed a figurative sense of complaint or grievance, possibly influenced by an earlier association between cattle and quarrelsomeness, and the corresponding verb soon followed. The phrase "beef up," meaning to strengthen or add substance, arose later, apparently from the idea of putting on weight or muscle. English "bovine" shares the same Latin ancestor, and "cow" descends from the same ancient Indo-European root.
