What does cockier mean?
"Cockier" is the comparative form of the informal adjective "cocky," meaning more arrogantly self-confident or overconfident. It describes someone whose assured manner has crossed into smugness or presumption — often implying that this confidence is excessive or not yet earned. The word is common in everyday speech and journalism, especially in descriptions of athletes, performers, and competitors whose bravado grows with success: a winning team may become cockier, a rising star may give cockier interviews. Its connotations are distinctly negative; while confidence is admired, being cocky suggests a lack of humility and an underestimation of rivals or challenges. The term derives from "cock," the word for a rooster, alluding to that bird's famously strutting, boastful bearing. Related forms include the adverb "cockily" and the superlative "cockiest." Because it is colloquial, "cockier" suits casual conversation, sports commentary, and informal writing better than formal or academic prose, where phrases like "more overconfident" would be preferred.

Etymology of cockier
"Cockier" derives from "cocky," which emerged as an English adjective in the late 16th to early 17th century from "cock," the word for a male domestic fowl. The rooster's strutting, aggressive self-display gave rise to figurative uses of "cock" suggesting swagger and boldness, seen also in words like "cocksure." The exact early history of "cocky" is somewhat obscure, but its connection to the bird's behavior is well established. It is unrelated etymologically to the slang sense of "cock" as a vulgar term.
