means The attitude or behavior of someone who judges and looks down on others based on social class, taste, or status, while fawning over those seen as superior.

from From "snob," a word of murky beginnings. It surfaces in 18th-century English meaning a shoemaker or cobbler, then a lowly townsman or apprentice. The charming campus tale claims Cambridge listed common students as "s. nob.," short for the Latin "sine nobilitate" — "without nobility" — but scholars treat that as folk etymology, not fact. By the early 1800s "snob" had flipped to mean one who vulgarly apes their betters, and Thackeray's "Book of Snobs" (1840s) cemented the modern sense of status-anxious pretension. "Snobbery" is simply the practice of being one.
