Does binging twice a week make you an alcoholic?

I don't drink every day, but when I do I tend to have 4+ drinks. Does this seem like alcoholic behavior? If so, I am able to curb it. Just curious. (I am aware of the calories, etc., luckily my exercise negates the effects, though I don't improve myself). I am a woman by the way. Quite small. 5 feet, 1 inch. 110 pounds give or take the time of year/giving birth.
