Alex is a kid with moneyed parents? A single mom living in apartments and a drifter bio-dad? Not trying to white knight Alex, but I grew up with some of these actual spoiled brats and just don't think the label applies. Is he a new age, hippie poser? Looks like it, but he's definitely not living on his daddy's dime.
Several definition of the term:
trustafarian
/ (ˌtrʌstəˈfɛərɪən) /
noun
(sometimes capital) British informal a young person from a wealthy background whose trust fund enables him or her to eschew conventional attitudes to work, dress, drug taking, etc
trustafarian (plural trustafarians)
(slang) A young person with the fashion sensibilities of a hippie, or any other countercultural trend, especially anarchism, Maoism, or punk rock, who subscribes to an unemployed, shiftless life of hedonism based upon an unlimited amount of funds (a trust fund).
trustafarian
priviliged white kids who subsribe to the hippie lifestyle (because they can) since they have no worries about money, a job etc. They can then devote their lives to eating organic, following Phish, and wearing dreadlocks (no need for job interviews).
"The term trustafarian is often applied to a trust fund baby or other privileged white person who deliberately affects the lifestyle of a true hippie or Rastafarian."
