noun
person attracted to older people; gerontophile
Slang term used in dating or personal ad contexts to indicate a preference for older partners. Often used in LGBTQ+ and niche communities.

プロフィールに「フケ専」と書いてある。

年上好き is a more general and neutral term for preferring older partners, while フケ専 is slangier and often implies a strong or exclusive attraction to significantly older people.
Compound of フケ (from 老け, 'aging' or 'looking old') and 専 (short for 専門, 'specialty'). Literally 'specializing in older people'.
