An alternative phrase for fecal matter lines in your underwear. Fudge smears occur around the corner from where lemonade is made. Usually caused from truly dedicated individuals diving deep to get that itch, cutting one off too soon, or misjudging the TTB ( time to bathroom).
Alternative use: the result of a Roomba pushing your dog's droppings across the floor.
These fudge smears are disgusting! I am not washing these. There is not enough bleach in the world...
