I wonder if there are any other words like foupe that can only be applied to animals not to humans? I have in mind the German distinction between "essen" and "fressen", the latter being the word for to eat applicable to animals only. I guess there are all the usual technical collective nouns like pride, herd, school, etc. Apart from that, anyone got any ideas? Many of them might be dysphemistic expressions for sexual intercourse, eg "rutting".
