A Jimmy Taco is the type of Taco you grew up having in America. Not a true south of the border taco, but now a staple of American-Mexican food.
The Jimmy Taco is always a hard shell taco with ground beef, lettuce, shredded cheese, tomato and sour cream and/or salsa. Variations can be made. The Jimmy taco will eschew traditional Mexican ingredients (crema, cotijia, cilantro) of the south of the border variety for ingredients you will find in any state of the USA (sour cream, cheddar or "Mexican blend" pre-graded cheese as examples)
The Street Tacos at Plancha are good, but the Jimmy Tacos remind me of my childhood in the 80s.
Fogey/fogy /fougi/ sl. (early 18C+, orig. Scot) old-fashioned, stuck-in-the mud.
Person with old fashioned ideas which he is unwilling to change: Come to the disco and stop being such an old fogey!
You think me an old fogeyand an old tory, his thoughtful voice said. I saw three generations since O’Connel’s time. I remember the famine. Do you know that the orange lodges agitated for repeal of the union twenty years before O’Connel did or before the prelates of your communion denounced him as a demagogue? You fenians forget some things. (James Joyce, Ulysses. Penguin Books,1992. p. 38)
