Phrase used to describe the putrid foul odor emanating from the ass of a man who has not showered in a few days perhaps longer.It is a culmination of ass butter, fumunda, and usually man snot as well. This can be toxic and has been fatal not to the offending person but to anyone within to close a proximity to the CRUSTY ASS and taint region of the odoriferous male.
In severe cases furniture sat on by a person smelling like a six pack of ass have had to be destroyed as there is no way to remove the stench.
