: "A fat lot of good that'll do you"
: What's the origin of "fat" with this meaning? Any ideas?
The adjective "fat" is used in many figurative senses such as "rich, abundant, fertile, capable of yielding excellent returns, plentiful". "A fat lot of good", like "fat chance", is just an ironic use of this type of sense. (VSD)
