horse sweat；men perspire;young ladies glow

这句话主要是强调婉言雅语的表达方式。它以流汗举例，sweat 只能用在动物身上，人用perspire, 但是男女还有区别，就像我们中文表达一样，男人是满身臭汗，女人却是香汗淋漓！！

字面翻译是：马儿流汗；男人流汗；年轻的女人兴奋喜悦
引申义为：战士和战马在辛苦搏命，为的就是年轻的女人那一刻的喜悦。应该是讽刺角斗场或者骑士对决等比赛的残忍和荒诞的

楼上说得不对．
“A study shows that female use more euphemisms than male do. There is a saying in English: ‘horse sweat; men perspire; young ladies glow.’ (Brock, 1973:73) Women use obscure word to express the action of sweat. And the difference of gender and age usually influence the choice of the synonyms of euphemism. For instance, there are a variety of expressions about ‘go to toilet’. Men use the expression ‘to shoot a lion’. Adults may say ‘to go to w.c.’. And children say ‘to go to the pot’.”[7]

意思是女人和男人的选词不同． 女人用词更．．．不清楚（其实就是委婉）
