BMI is a load of crap because muscle weighs more than fat. A built guy could register as overweight on that scale.
Your body isn't made just out of muscle. There is fat in there, there is bones, there is other types of tissues and more things that have different masses.And BMI is a comparison of your height and weight. If you are over-weight that means you weight more than an average person but are shorter than an average person. AKA a chubby mother forgeter.
