Makybe Diva is the seven-year-old mare who entered the Australian horse racing record books by being the first racehorse to win three consecutive Melbourne Cup races (2003, 2004, 2005). Condsidered a thoroughbred.
As a result, any amazingly attractive, sexy woman that would be referred to as a thoroughbred, can be more discretely referred to as a 'Makybe'
Mason - Look at that stunner over there!!
Joey - Yeah, What a Makybe...
