What does eyeballed mean?
"Eyeballed" is the past tense of the informal verb "to eyeball," which carries two related senses. The first and most common is to estimate or judge something visually rather than measuring it with instruments — as when a cook eyeballs the amount of flour needed instead of weighing it. The second is to look at someone or something directly and deliberately, often with an air of scrutiny, suspicion, or appraisal. The word belongs chiefly to informal register: people say a carpenter eyeballed a cut or a bouncer eyeballed the queue, but formal or technical writing would favour "estimated" or "measured." Its charm lies in the image it evokes — turning the naked eye into an all-purpose measuring tool. Widely understood across the English-speaking world, it adds colour and candour to descriptions of rough judgment and frank staring alike.

Etymology of eyeballed
The noun "eyeball," meaning the spherical organ of sight, dates back centuries in English — Shakespeare used it in "The Tempest" in the early seventeenth century — and is a straightforward compound of "eye" and "ball." From this noun grew the verb, first attested with meanings relating to looking or staring, and later extended in twentieth-century American slang to the sense of estimating by eye. Related compounds such as "eyewitness" share the same transparent use of "eye" as a formative element.
