Bender: That's impossible!
Ah, the Ego.
The part of the psyche that defines you as an individual, and considers itself (read: you) a separate entity from the rest of nature and even the entire cosmos, the ego is what encourages people to care about their personal wants and needs instead of just being an Extreme Doormat. While necessary in moderation, allowing one's ego to become overinflated leads to self-centered and downright embarrassing behavior.
The character who fits this trope seems to think that the world ought to revolve around them and their every little whim, and is ready to walk all over other people in order to get what they want. This character expects others to wait upon them hand and foot, make way for them on the sidewalk or let them cut ahead in line, help them first even if there are other people in greater need, and sacrifice their own best interests for whatever he or she demands. They don't care about how their actions might harm other people, yet display Moral Myopia when someone else does something to harm or inconvenience them.
A healthy ego exults the strengths of an individual in an overt way, which—on balance—can benefit everyone. An unchecked ego, however, is mainly preoccupied with blocking out "unacceptable" thoughts that are hurtful or belittling to itself, even tuning out the entire world if necessary. Toddlers have this attitude by default, as their brains are not developed enough to understand that other people have different viewpoints. We're less forgiving of (non-disabled) adults who behave this way, also termed assholes.
Warning: The limits to which the human ego can expand have not yet been reached.
When the cause of the attitude is being raised in a family of great power and wealth, you have a case of the subtrope Royal Brat. For religious cases, see Egocentrically Religious. Overlaps with Moral Myopia when debating the rights of others versus the rights of oneself. When combined with a massive sense of self-preservation, we get the Dirty Coward.
