It is when a Clean Thursday(a holiday for cleaning up your house and washing yourself) turns into Dirty Thursday, when you make love(have sex) whole day long.
Оh, last week was a Clean Thursday, did you take a bath and make the cleaning?
Honestly, a boy was at my place and we were loving each other whole day long, it was really a Dirty Thursday!
