a nose organ that smells pheromones you'll never consciously notice, judging your every flirtation

means The Jacobson's organ (vomeronasal organ) is a small paired structure in the nasal cavity of many animals that detects pheromones and other chemical signals, separate from ordinary smell.

from Named for Ludvig Levin Jacobson, a Danish anatomist and physician who described the organ in the early 19th century — so the surname is simply his, attached forever to the bit of nose he catalogued. The fuller anatomical name, 'vomeronasal,' comes from Latin: 'vomer,' the plough-shaped bone in the skull, joined to 'nasus,' the nose.
