What kind of dinosaur is the egg stealer?

I'm curious, could you elaborate on the "egg stealer" dinosaur you mentioned? Are we talking about a specific species known for its tendency to pilfer dinosaur eggs? Or is this a colloquial term for a dinosaur that exhibits predatory behavior towards nests? If it's the latter, perhaps we're discussing a carnivorous dinosaur like the Tyrannosaurus Rex or the Allosaurus, which were known to prey on other dinosaurs, including those that laid eggs. However, if you're referring to a specific "egg-stealing" dinosaur, I'd be intrigued to learn more about its unique characteristics and behaviors.
