What is the correct definition and usage of the term "tids and bits"? I tried googling but nothing turns up, not even a definition.
Personally, I have never heard the phrase that you are using being used. The correct usage is tidbits.
Here is the definition that Google gives when you define it:
tidbits plural of tid·bit (Noun)
A small piece of tasty food. A small and particularly interesting item of gossip or information.
