Is there divine retribution for halfheartedly cursing God?

Assuming for the sake of argument that you believe a) in the Judeo-Christian God and b) that said God exacts divine retribution on those who curse Him, is there divine retribution for a halfhearted cursing of God?

Say, for example, that I’m walking down the street with a friend of mine and a man attempts to hand us a Chick tract. My friend gives him the finger, and I facetiously say “God wouldn’t like that.” If my friend says, “God can blow it out the divine ass,” will this draw divine retribution of the type that philosopher Soren Kierkegaard believed his family faced after his father cursed God as a young man, does God have a better sense of humor than that, or is there a third answer I haven’t thought of?

Aw Christ, I hope not.

Half-heartedly cursing God gets you sent to Heck when you die, where you suffer eternal mild irritation.

Even if you buy into it, all religeous questions end up with circular arguments. Same as time travel. That’s a good reason to believe in neither.
