Please define what this is:  gaiustlives .  Google search turns up 1
result on Morningstar - two people use it in a discussion with each
other.  Need Premium Morningstar membership to ask them directly.

If I'm not mistaken, one of the discussion members is using the screen
name "gaiuslives" and another discussion member is simply misspelling
it (by adding a "t") when he is trying to refer to him.

   Have a good day.

I agree with thither. This is almost certainly just a misspelling of a
username. As to why someone would choose 'gaiuslives' as a username, I
speculate that this might be a reference to Gaius Octavian, a
character in HBO's series "Rome." Gaius is a very common Roman name,
but Octavian is probably the most prominent pop-culture reference.
Gaius was also the praenomen of Julius Caesar.
