I heard in a movie (Kung Fu Panda 3)
How does it feel? (referring to a battle armor) Do the hinges hinge?
"Hinge"'s definitions on ODO are:
[WITH OBJECT] 1. Attach or join with or as if with a hinge.
1.1 [no object], with adverbial of direction (of a door or part of a structure) 1.2 hinge on [no object] Depend entirely on.
This does not include the usage in the movie, which is intransitive. What does that line mean?
