on the hoof
an exceptionally masculine and muscular man.  A compliment used in the gay community to refer to a man.  It is not used lightly, usually for unusually sexy and muscular men.  A mix of beefy (perhaps how the term was created), masculine, and sexy.  
Wow.  That man is on the hoof.  

Some would say Thomas Jane in Punisher, or Hugh Jackman in X-men 3 were "on the hoof".
