A British word for a rich, upper-class person — and the word itself does the judging. You do not call someone a toff as a neutral description of their class; you call them a toff to say that they are privileged, that they look down on ordinary people, and that they did not earn what they have. The picture behind the word is very specific: expensive private school, an accent that announces it, family money, and no idea what things cost. Class is a live and touchy subject in Britain in a way it is not in Taiwan, and 'toff' is one of the words that carries that history. It appears constantly in political argument — a newspaper calling a government 'a cabinet of toffs' is making a real accusation, not a joke. It also has a lighter, teasing use between friends: if someone orders an expensive wine, you might call them a toff and everyone laughs. The tone depends entirely on who is speaking and to whom. It is informal, distinctly British, and mostly unknown in America. It is also becoming slightly dated among the young, who now more often say 'posh' (which can be neutral or even admiring) or use sharper political words. The nearest relatives are 'posh boy', 'snob' (which is about attitude, not money), and the older 'nob'.

有錢的上流階級人士、貴公子（帶貶意，暗指這人靠家世、看不起平民）。台灣語感最接近的是「高級人」「天龍人」——都是用來酸出身好又不食人間煙火的人。不要譯成中性的「紳士」，那完全丟掉了嘲諷的味道。
