Limey (also Lime-juicer).
Increasingly uncommon American terms for an Englishman. They appear to have been inspired when American sailors noted the compulsory British practice of giving sailors lime juice as an antiscorbutic, although some support the notion that limey, at least, derives from the expletive "God blim’y" (for "God blame me," or the more powerful "God blind me"). From an American standpoint, the term seems to have begun as a seagoing slur but later was more commonly used with some degree of affection, such as during the two world wars. Both terms can refer to a British sailor or an Englishman, while lime-juicer has also been used as a slang term for a British ship.
