toff: [19] Toff probably originated as an alteration of tuft [14], which was used from the 18th century as an Oxford University slang term for a ‘titled undergraduate’ (students who came from noble families wore a gold tassel or ‘tuft’ on their caps). Tuft itself was adapted from Old French tofe or toffe ‘tuft’, a word of Germanic origin. => tuft[toff etymology, toff origin, 英语词源]
