“校花”的英文说法最常见的有school babe和campus belle两种。

Babe is a word used to address a young woman, or your wife, husband or lover, usually expressing affection but sometimes considered offensive if used by a man to a woman he does not know. Now many people use it to refer to an attractive young woman, for example: she is really a babe.

Babe这个词是对年轻女子或爱人的昵称，男子用以称呼不相识的女子则有冒犯之嫌。不过，现在很多人都用这个词来指代年轻貌美的女子。例如：她真是个美女。

French word "belle" means beautiful woman, hence, campus belle is the most beautiful girl in the school.

Belle是个法语词，意思是“美丽的女人”，那么campus belle也就是学校里最美丽的女子（即“校花”）了。

　　“校草”的英文表达呼声最高的当属school hunk了。

Hunk is a slang term for a sexually appealing man, a person who is sexually attractive or a well-muscled, sexualized man.

Hunk是个俚语表达，指性感有魅力的男子，或者身形健壮、有吸引力的男子。
