2.
A type of a Taco, in which the meat is heavily seasoned with Oregano, and topped with ketchup. Named for a former roommate, Josh, whose family might possibly have invented this idiosyncratic blue-collar Italian variant on the most mainstream of Mexican dishes.
"Why the hell does it smell like chiles and spaghetti in here?"
"Oh, looks like my roommate's been making his famous, weird-ass Jacos."
"What the hell is a Jaco?"
"Here, try"
"Not bad. But who the hell puts oregano & ketchup in their taco mix?"
