dilettante

An amateur, someone who dabbles in a field out of casual interest rather than as a profession or serious interest.

A person with a general but superficial interest in any art or a branch of knowledge.

A comment like "The author is a self-important dilettante." is really nothing more than a pretentious version of "u r a fag."

“Call me Zack Ransom.” “And I'm Gilbert Manhandle, literary dilettante with a gambling addiction.” “Nobody's going to remember that. You can be Zandy Billups.” “Fine. But I'm still a gambling addict.”

Pertaining to or like a dilettante.
