Big Unit 

Nickname of future hall-of-famer and K/9IP king Randy Johnson, thus giving him the distinction of being the only baseball player to have a double entendre for both his given name and his nickname.

Randy's pitching makes every pitching fanatic's unit big.

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"
