But that's a culturally determined example. Twinkies, thankfully, never made it across the Atlantic.

Alternatively the second speaker is expression a sentiment that the first speaker has wolf down the last of the Twinkies in the house and that they are resentful of the action. Without a (much) larger context we can't read into that anecdotal example any real sentiment, opinion or reputation.
