When I first saw this term (going through the English language filter in my mind) I speculated that it might refer to people such as myself, who enjoy reading and writing a really good essay….

But no, it is in fact a French term, referring to men, employed by brothels, who have the sole task of performing sexually arousing acts with the sex workers, to engage and entice the shyer of the potential male clientele to avail themselves of the women’s services.
