the.com/cut of your jib

18th-century sailors judged ships by their sails; now strangers judge you by your vibe.

means It refers to the general look, style, or manner of a person — the overall impression they give off at a glance.

from Comes from old sailing days, when a ship's jib (its foremost triangular sail) had a distinctive cut or shape that experienced sailors could use to identify a vessel's nationality or make from a distance — friend or foe, before you got close enough to be sure. By the early 1800s, sailors had stretched the phrase ashore, applying it to people: you could size someone up — trust them or not — just by their general bearing, the same way you'd size up a ship by its sail.
