Выражение встречается в следующем контексте:

When you love someone, you tell yourself that they're not like other people, that they too special for that. But Paul paces the bars like any other caged lune*. Why be surprised? This white-toothed fast-paced luned that hurled at me jaws open is Paul just as much as the one, who talked his way into my life. There's nothing in his cell that wasn't in my bed.
