A cheap Mexican eating establishment which is usually located on your local state street. It will most likely have a California burrito as an item on the menu. It is referred to as 'Dirty' as it is usually cheap, greasy and quick as opposed to a classy 'sit-down' Mexican restaurant.
Bob just texted me back, and he says he just wants to get Dirty Mex before the game because he is broke.
