3rd definition from Urban Dictionary:

An increasingly prevalent condition found primarily in young heterosexual American women. Characterized by (1) unrealistically high expectations; (2) materialistic conduct; (3) a sense of entitlement; (4) exploitative behavior; (5) feelings of superiority; and (6) a lack of regard for society’s rules and mores.

Princesses believe in their own exceptionalism and usually hail from wealthy or upper middle class families. They are quick to describe themselves as "awesome" or "amazing" on social media. Given their access to resources, they are typically attractive, although rarely naturally beautiful. In public, princesses may attempt to cut in line, believing their time to be more valuable than others’. They enjoy berating cashiers, waitresses, and other service workers. Princesses often walk down the wrong side of the street but refuse to yield the way to oncoming pedestrians.

Princesses also typically maintain unrealistic dating expectations. A princess may, for example:

  • Stand 5’2” yet refuse to date men under 6’
  • Demand a “successful man” despite having never worked a day in her life
  • Display the arrogance typically found in 10s as a 6.5

The prognosis for Princess Syndrome is largely unfavorable. Management options typically include:

  • Cessation of allowances and support funds
  • Full-time work obtained through independent efforts

In some cases, full remission has been achieved, but most patients who present with Princess Syndrome typically retain it for life.

Since her profile contains nothing but mentions of how "amazing" she is, she might have Princess Syndrome.

If you spoil your daughters, you run the risk of causing them to develop Princess Syndrome at an early age.
