- hot dog
[hot dog 词源字典]
- also hotdog, "sausage on a split roll," c. 1890, popularized by cartoonist T.A. Dorgan. It is said to echo a 19c. suspicion (occasionally justified) that sausages contained dog meat. Meaning "someone particularly skilled or excellent" (with overtones of showing off) is from 1896. Connection between the two senses, if any, is unclear. Hot dog! as an exclamation of approval was in use by 1906.[hot dog etymology, hot dog origin, 英语词源]
