What is meant by the term "Glocked Brass"? I am just starting to reload again after several years away from the hobby.

It refers to the fact that the chamber on a Glock .40 is not "fully supported", as a result, there is a slight bulge near the base of the case that can create problems when chambering in a gun with a really tight chamber.
This is also something that has grown in status to something resembling an urban myth! Virtually all chambers in all semi-auto pistols are not fully supported. There is always a small area at the feed ramp that is unsupported. If it were not, then the action would not work correctly. Early Glocks were said to be less supported than they are now.
The term is a lot like referring to all facial tissues as Kleenex. It's a generic reference to this general reloading problem.
There is another aspect to this that is a bit more reality based, the chamber of a Glock is a bit "looser" than some other guns and third party barrels. The reason is to make feeding a variety of ammunition easier. This may (or may not) contribute slightly to this. In any case, you can chamber almost anything in a Glock, including reloads. But if you take cases shot from a Glock and reload them, they may be a tight fit in some other guns.
AFAIK, this only relates to .40, however some people with really tight match barrels say they have a similar problem with 9mm. In any case, it has become the fashion to buy an undersized sizing die from EGW. This is a Lee die that has been modified to size further down the case. You can find a couple dozen threads on this.
