lignogenic 

A quasi-medical term derived from the Greek root words, lignos meaning "wood" and genesis meaning "to give rise to". The term refers to someone, usually a nubile woman, who causes you to get an erection.

Sarah Palin is pretty hot but her daughter Bristol is more lignogenic.

lignogenic potential 

From the Greek, combining lignos, the word for "wood" with "genesis" meaning to give birth to. This pharse describes the ability a particular woman has to inspire an erection. Not to be confused with a perfect erection, the so-called "lignogenesis perfecta".

Man, this disco blows. Not one of these bufforillas has any lignogenic potential.
