This is a metaphor (I think).
If Stanley Tucci was eating a whole roast chicken in front of you, he would approach the meal shyly and then rip into it. He would slather himself with grease because he would disregard what other people think and only consider how to enjoy the feast with the most gusto possible. And he would be totally unashamed doing it. When he comes close to finishing all the meat and even the skin, he would take each bone and suck any residual flesh off of it.
That is just the kind of actor he is.
