There is no scenario in which this is not alcoholic behavior, whatever we want to label the people engaging in it. Her defensive answer to his questioning it makes it even more likely she's an alcoholic, especially because she made it a personal attack. Some of the people engaging in this type of drinking, as I did when I was in college, will move on from it and live lives as non-alcohlics. Nevertheless, it is alcoholic behavior and it is an issue for him.
The sad part is that many of the people doing it are alcoholics, and cloak it in the "it's a phase" language in order to excuse it or hide it.

I especially see this in the college age drinkers.
So, to say that a person who drinks that way is automatically an alcoholic is, IMHO untrue.
Many of those young people will grow up, get tired of the hangovers, and never go back to drinking that way again.
But, as naive said, if it's a problem for you- it's a problem period.
