After banging your partner, you turn on the dust ridden ceiling fan for all of the dust to fly off on the bed, but most importantly, her muff.
I accidentally pulled a dust in the muff on my girl last night and she told me she wasn't a fucking swiffer and left.
A cloud of dust blown from an arse, when a powerful fart is expelled.
Wow man, did you see that? That man has major arse dust.
