What is meant by "God's Omnibenevolence"?

I am wondering what people mean by God having omnibenevolence. I see it having a couple meanings; one being God loves all, which I agree with. Another one is if God is all good, which obviously He is. He created the morality and is above it. He decides what is good and what is bad. Or people good mean He is infinitely kind. Kindness according to the oxford dictionary is > "the quality of being friendly, generous, and considerate." I would argue that God is not infinitely kind, otherwise there would be no hell. or perhaps people mean something completely different. What's the general consensus? edit: i probably just don't understand something
