To take a long time processing something, or you're "stuck" in one generation, or to just be dull and stupid in general.
1) You take a long time to find a proper response or reaction towards certain events, you can't spontaneously reply or response to things that occur. You need to spend a lot of thought on your intentions and objectives before you put them into action.
2) You are quite dim-witted, and considerably stupid. Again, it takes you a long time to process actions, and you
think before you speak. You show a sense of carelessness, and are most likely rather clumsy.
3) You aren't quite intact with the modern times, as if you are stuck in a certain generation. Many old-timers are presumably perceived to be stuck in their times, and stick with what they've
done over the decades. Being
slow-minded may mean that you don't respond too well to change, or just don't want to change.
"Julia is a
slow-minded imbecile that just wants everything her way, and she doesn't even know what she wants to do when she gets it."
"Granny
Gertie is very slow-minded, and still thinks that all black people are evil and should be killed by
the KKK. Hell, she wants to bring the KKK back!"
