Protein serves as the building blocks for muscles. The thought is that if you eat more protein, you'll build more muscle. We've even heard of people eating upward of 500 grams of protein every day, just with the goal of getting swolled up.
First, you need to actually train to build muscle. Eating protein without a training program won't do much good. Second, your body cannot absorb more than 20 grams of protein at a time. So stuffing your face with 10 chicken breasts and a protein shake is essentially a waste of money.
Instead, eat about 1 gram of protein per pound of body weight (the exact number depends on your goal) as part of a comprehensive diet and training program.
