Originally coined by women in the late 1980's as "Financially Attractive" when talking about an ugly guy, this new definition is now used by the "Wiser" Gentleman ( A male of approximately +35 years). A man who has probably just come off his 3rd serious relationship with a "Hot sort" ( A feamle aged 25 +/- 5 years old) since losing his virginity and has no coin left due to her Insta lifestyle requirements. The said "Wiser" gentleman has now realised that the Hot sort is not worth the time nor financial effort and is happier with someone who has a better paying career, brains and at sometimes alot older, rather than the "Hot sort" looks he has committed to in the past. Hence the male equivalent term "Financially Sexy".
