Greg John Rowell played cricket for QLD in the domestic cricket competition, called the Sheffield Shield (now the Pura Milk Cup) in Australia during the mid-90's.
The term Greg Rowell is used in Australian rhyming slang, meaning to go the growl or to perform oral sex on a female's genitalia.
The equivalent to a female performing oral sex on a man is Bretty Heady or to give head.
