What does "solid title" mean?

Hi,
It could mean that. You need to provide us with a context for this phrase.
Can you tell us the sentence, and where you found it?

Let's say if i started a thread on a forum such as "How often do you drink" then someone just replied"solid title", what does that really mean?

It's an odd way to reply. It sure sounds like the person thought you had picked out a good title for your thread, but he didn't actually give you the answer you were hoping for, did he?

Thanks a lot

In real estate, it would mean a property with a valid title policy issued by a reputable title company.

For automobiles, it would be a car that has a certificate (title) issued by the state.

But that doesn't have much to do with the poster's example about starting a thread about drinking, does it?

I was very confused by that, so just ignored it.
