What is "crave" in this context? This is already an unconventional action for an interface. Am I to assume that you are trying a new variation on "like" / "favorite"? Since it doesn't use a conventional name, does it do something different? If it is just essentially a "like" action, do you have sufficient reason to break from convention? If an affluent white male interface-creating technologist in the bay area like me doesn't immediately know what the action does, maybe the unconventional icon isn't the only deviation from convention that's causing confusion.
