Derivative of the Italian word for cheese "formaggio." Forgotggio describes the inability of any Subway sandwich artist (SA) to remember which type of cheese you desire for even two seconds after you tell them, thus necessitating them asking you again, or at minimum confirming before placing it on your 12" chicken and bacon ranch or whatever.
Made even more annoying by the fact that they can remember over a half dozen vegetable requests with no difficulty.
Me: Hi, I'll have a 6 inch tuna on wheat please.
SA: What type of cheese with that?
Me: Pepper Jack please.
Me: No thanks, man, its a tuna sandwich.
SA: Okay. . . what type of cheese again?
Me: PEPPER JACK! Looks like you have a case of forgotggio.
SA: Yeah, I guess. Do you want lettuce, tomato, onion, pepperoncini, jalapenos, green peppers, oil and vinegar, and salt, like last Thursday?
Me: Yep! (shaking head in disapproval)
