Wrong side of the oven

[Stevenloan]

Spend With Pennies: This easy pineapple teriyaki chicken is a delicious weeknight meal.
B: Looks yummy but I'm not going to join a damn group where they can't give you a recipe without joining.
C: B, This is a site, not a group. The recipe shows. I use many recipes from Spend With Pennies.
D: B, somebody woke up on the wrong side of the oven today. Hope your day gets better, ma'am.

- Hi guys! Spend With Pennies is a Facebook page. What does D mean by "woke up on the wrong side of the oven" in this context?

Your answers will be highly appreciated.

There's a common idiom, "to {wake up on / get out of} the wrong side of the bed", meaning "to be in a bad mood". Person D has just adapted it for the context of this discussion.

I can understand what they're getting at, but I don't think this latest twist on the idiom is likely to become widespread.
