Precisely what Henri Poincare warned Cantor not to do (i.e. not to think of infinity as a completed thing)
Ah joy, "completed infinity".

Just for your information, I have never encountered somebody who uses that terms that could give an even quasi-rigorous account of what the term means.

From observing people who use it, I quite honestly believe that it literally means "I am unwilling or unable to engage in one more layer of abstraction, and thus have failed to recognize that we're talking about the same idea." (I don't mean insult by this, except possibly in the 'unwilling' case)
