That's a good one. There must be a lot of material in Grose's work.
An American journalist a hundred years ago wrote "The Devil's Dictionary" not of slang, like Grose, but as a cynical look, from an American perspective, that is often just space-filling and 'humorous' poetry but which can be uncomfortably accurate.
The definition of "Man" is:
An animal so lost in rapturous contemplation of what he thinks he is as to overlook what he indubitably ought to be. His chief occupation is extermination of other animals and his own species, which, however, multiplies with such insistent rapidity as to infest the whole habitable earth and Canada.
