Monster Mac Slammed

Monster Mac Slammed is a fusion of three big macs together. By this process of fusion, you get a Monster Mac Slammed that is incredibly deadly. Putting three big macs together can be quite an experience. One may ask, "Can I just buy three big macs and eat them individually?" The answer is obviously yes; however, you will not get a Monster Mac Slammed experience. Monster Mac Slammed is equal to 1/4 of Chuck Norris round house kick. Except, in this case, this will be a deadly kick towards your heart.

Monster Mac Slammed is far too powerful for McDonald's to contain as a subset within the corporation.
