Aye, that's the scrub.
Ok, anyone out there ever work in food service? Do you remember those green 3M scrubby pads? At Little Caesars we called them Green Meanies. Because they were green and... erm, mean. (Come on, like you could come up with something better?) After using them for a week or so they'd be seriously trashed. The edges would be frayed, food particles stuck in them, black spots from where you'd scrubbed the pans, just... well, just like this poncho.
