What does Pluto square Saturn mean in...?

What does "Pluto square Saturn" mean in a synastry/compatibility chart? Why is it considered bad?

Idk If its bad...i have sat sq sat with my wife and were kinda glued to eachother, Its like a karmic thing.

Wthi pluto it might cause destruction and renewal...not necessarily always bad.

I read it was more about the difference in "ages"?

No, pluto and saturn are independant from eachother, time wise.
