When someone passes out, you might take a fat poo then rub some all over the back of their neck, thus giving them a turd mullet.

A Nut Mullet is when a man shaves exclusively the visible part of their scrotum. In doing this they leave the back and bottom of the ball sack leaving what can be seen as a mullet for your nuts. This is likely to be seen on the sack of a married man, a man in a committed relationship or a man who's given up all hope on life.

Business on the top, party of the bottom. This allows you to appear professional on a business video call without having to wear pants or shoes.
Jim wore his clothing mullet to work because he could only be seen from the waist up - and he wanted to be comfortable.
