When consuming McDonald's or other fast food items, you eat until the point that you are full. However, the moment afterwards your fast food feast, you feel bloated and truly American, which will necessitate a McBreather; a moment of lethargic proportions. You tend not to move, you feel like if you eat anymore food, you will throw up, and within in thirty minutes to an hour, you are capable of eating again.
