Ogres usually don't show up in the stories I read. Just DnD and Warcraft really come to mind. But I imagine Shrek Ogres show up alot, too.
Looking it up, Ogres are described as having two key traits:
They are large, with oversized heads.
And they eat people, particularly human children.
These traits have also been given out to other creatures like Giants, Cyclops, Oni, and so on. In these cases, the creatures are described as Ogres or as having Ogre-like traits. Like Giant Ogre, One-Eyed Ogre, Demon Ogre, so on.
So as long as you give them those two traits, it's an Ogre. They're a fucking ancient monster, so you have to really distill the details to get a good definition.
