There is no specific recipe for slut sauce. It's basically whatever you have in your fridge that isn't completely rotten put in a pan and simmered for a while. You can put it on whatever the hell you want.
It gets its name because in back in the day in Italy, the whores, who were poor and couldn't afford good ingredients, would cook up whatever they could find and put it on their pasta.
It is also known as "Puttanesca".
"Shit bro, nothing sounds good for dinner."
"Looks like it's slut sauce again."
