'Filth knuckle' when you're knuckle deep in pussy and the lass hasn't the best personal hygiene... when your finger(s) come up for breath you have a suspicious brown stain on the back of your knuckle(s).
I've never had such bad filth knuckle as last night... it was like I'd been eating dark chocolate with the back of my hand.

Lady of dubious looks and morals. Often found frequenting Walkabout in Bristol circa 2000-2006. Many of which go on to get ploughed that evening.
