A general name for a cat; also a parcel of rags fastened to the end of a stick, to clean an oven; also a figure set up in a garden to scare the birds; likewise an awkward woman. The cove’s so scaly, he’d spice a malkin of his jazey: the fellow is so mean, that he would rob a scare-crow of his old wig.
