Randy Johnson the former big league pitcher who pitched for several teams throughout his brilliant career was nicknamed the big unit.
Johnson was called the big unit for several reasons . He was the tallest pitcher in major league history measuring 6'11" and being a southpaw, it was almost impossible for lefties to get a hit off Johnson. Furthermore, there are several words that mean penis such as dick, cock, johnson....etc. So, Randy Johnson, who was known as a real asshole and physically resembled a huge penis was given the nickname "the big unit"
