The financial version of an "incel" (involuntarily celibate, sexually frustrated). A typical fincel suffers from economic illiteracy, which results in
poor career and life planning decisions that lead to a life of
poor financial health. This financial dissatisfaction is often a combination of a college degree that is not marketable, large amounts of student debt, etc.
Like incels, a fincel often turns to extremist political/social views that involve harming those that are economically literate and financially stable. Fincels resent
society.
Jim: hey
whatever happened to Tony? He was excited to graduate with an art history degree.
Scott: Tony lives at home still and works as an Uber driver and sometimes
bar tends. He's evolved to a bitter fincel and hates successful
people.
