It's a Friday and you ask your friends to go grab a bite to eat before getting ready for the party that night. However your friend refuse. Why is this? Everyone knows you have to eat before drinking to prevent yourself from getting totally wasted and to avoid alcohol poisoning.
The same pattern repeats every weekend until you notice a trend: People are not eating the day they plan to go out to reduce the calorie intake and to help them get drunk faster, a new trend known as "drunkorexia."
