A Twilight Boner is what happens when an obsessed Twilight fan boy or girl sees/hears/reads anything that has to do with the Twilight series.
"Today I saw the New Moon preview and totally got a Twilight Boner."
"I got the biggest Twilight Boner when I heard that the Twilight stars were going to be at the mall signing autographs!"
