- Inside baseball - I can't tell if I like this one because it is always used in the context of some secret knowledge (the best knowledge!), or if the idiom has inherent worth. After all, I am not the biggest baseball fan in the world (ChiSox!), but any kind of respect paid to those who would study a field to within an inch of ridicule has a tip of the hat and five on it from me.
- Hit the spot - Again with the food idioms, I know. What is the spot? Is it the bullseye of your consumptive target? What happens when you hit it? Are you supposed to feel some sense of satisfaction, as though you had trained yourself over time through repetitive practice sessions to find exactly the right combination and amount of foodstuffs to satisfy your dietary needs? If so then by all means, because that sounds laudable now that I've written it out, but this phrase is far more often uttered in response to less condonable desires.
