noun
debauchee; libertine; hell-raiser
Refers to a person who leads a dissolute, self-indulgent life, often involving excessive drinking, gambling, or sexual promiscuity. Somewhat literary or old-fashioned; in modern casual speech, terms like 遊び人 or 道楽者 are more common.
彼は若い頃、放蕩者として名を馳せた。
In his youth, he made a name for himself as a libertine.
A debauchee's lifestyle doesn't last long.
Similar meaning but emphasizes indulgence in hobbies or vices as a way of life; slightly less formal than 放蕩者.
Compound of 放蕩 (ほうとう, 'dissipation, debauchery') and 者 (もの, 'person'). The exact historical derivation is uncertain, but the spelling is conventionally associated with the meaning of a dissolute person.
