Hi - one thing to keep in mind is that often English doesn't have just one word to express such complex scenarios. German has a tendency to create words which compound onto each other, but English doesn't.
For your question, it really could be anything (a feeding frenzy is actually a lot of messy, fast eating and it doesn't apply here). Such as:
- "You finally cooked something good!"
- "Wow, you learned how to turn the oven on."
- "It's so much better when we go to the butcher instead of picking up roadkill."
And none of these are nice -- and they aren't even particularly humorous. They're a bit like what are called
left-handed compliments, where it sounds like you're saying something nice, but you're really getting in a dig.
