An office tradition wherein a group of employees, usually in the computer programming field, will go to lunch at a Mexican restaurant and pound over-priced, over-sugared margaritas for 2 hours. The most common outcome is that absolutely nothing gets done at work between the hours of 8am - 11:30 am and again from 2pm - 4pm. Friday was historically the day that this happened, but more modern workplace environments can see this on any day of the week. After 2pm you may find more seasoned Margarita Fridayers at the closest bar to the restaurant hitting on the day staff.
IT'S FUCKING MARGARITA FRIDAY BITCHEZ!!! IS ON THE BORDER OPEN YET???
