Tick: (Verb) As in the phrase: "what makes someone tick;" what motivates someone.

In her quest to market herself to the point of no return, Miley Cyrus has signed a seven-figure book deal with Disney; which will apparently feature "never-before-seen photos, family stories and a look at the star's inner circle."

That sounds great on paper, but I think there's a flaw in Disney's plan, in that why would anyone pay for those things as long as Miley Cyrus has Myspace and YouTube accounts? Thanks to modern technology, we've already seen what makes Miley Cyrus tick. Which, based on my best educated guess, would be a healthy mix of narcissism, stupidity and probably diet pills.
