A woman so incredibly hot that men are compelled to send her pictures of their penis, half flaccid or not. Made famous when the legendary #4 inches, Brett Favre, did just that (allegedly).
Brett: "Do you think I should get hard before I send these pictures of my penis?"

Security Guard: "How can you not be hard after seeing Jenn Sterger?"
