Used in the same context as asshole and meaning the same thing, assel is less conspicuous and far less noticeable to someone who doesn't know what it means.

An assel is a tassel spun or twirled by a performer on their behind. Not to be confused with a 'tassel' commonly used by burlesque performers on their breasts. 'Ass' + 'Tassel' + 'Assel'.
Did you see that? They were spinning their assels so fast I thought they were going to take off.
