What is Slut's Wool?
1.
another name for 'dust bunnies', large conglomerations of dust and other debris that collects in the corner of rooms, normally around skirting boards.
Before 'slut' became common-usage for a woman of promiscuous temperament it was also used to describe a slovenly girl or woman who was untidy or did not clean her house.
'Have you got a hoover, because I don't think I can get rid of all this slut's wool with just a broom'
'I swear, this flat is so dusty, give it five days and already there's slut's wool under the beds'
