In colloquial use by laypeople, 'theory' is roughly a synonym for 'educated guess'. So calling something someone says 'just a theory' is a way of saying it's speculative.
In science, what most people call a theory would be referred to as a hypothesis. The next step is to attempt to disprove the hypothesis by experiment or comparing it to predictions that would follow if it were true. Only if the hypothesis survives repeated testing is it considered confirmed. A scientific theory is based on, and explains, multiple confirmed hypotheses. There is much in 'theoretical' physics that would be better described as hypothetical, but the theory that the universe was once in a hot dense state that underwent rapid expansion that continues to this day is as well-supported as the theory of gravity.
