The stain on your underwear as a result of sharting, sometimes permeating to the outer layers of your clothing. Usually accompanied by a putrid odour. Biohazardous.
I thought I just farted, then I checked my underwear and saw a huge krassenstein.
I could smell the krassenstein as he took off his trousers.
As I walked into the room, the dog ran straight to me and nuzzled my krassenstein
Floating turds that will not flush.
I've flushed this toilet four times and this krassenstein just won't go away.
