Food/drink going straight to waste.

Wondering about excess intake of food and drink calories going to waste rather than being absorbed.  Personally doing old school bulking for months on end and observing other having huge cheat meals or binge drinking of high calorie beer, it seems there is a point where this excess is going almost entirely to waste with little absorption of calories/nutrients.  Obviously 5000+ calorie binge eating/drinking doesn't fit well into a health lifestyle, but it also is obvious that your body is expelling much of this for some people without huge swings in weight. Any thoughts on this, and can it be accounted for while doing a macro/calorie based diet.
