Once on a Lord-Mayors day, in Cheapside, when6 Sir-reverence: "Human excrement" (Oxford English Dictionary, s.v., sense 2.a)
Skulls co'd not well passe through that scum of men,
For quick dispatch, Sculls made no longer stay,
Then but to breath, and every one gave way:
For as he breath'd, the People swore from thence 5
A Fart flew out, or a Sir-reverence.
