no stinking euphemisms

They probably had different euphemisms. Speaking of which, my favorite euphemism is faeces for 'shit'. In Latin as the Romans spoke it, there were two words, merda (whence the Romance words) and stercus. In the Middle Ages, some medical person started using faeces, the plural of faex, which means 'dregs, lees' as a euphemism for 'shit'. Excrementum was another one, but an older one; in Latin it could refer to anything expelled from the body, like 'snot'.

Ceci n'est pas un seing.
