"エロガキ" (erogaki) is a Japanese term that combines "エロ" (ero), short for "エロチック" (erotic), and "ガキ" (gaki), meaning "child" or "kid." Together, "エロガキ" is a somewhat derogatory slang term used to describe a person, usually a young male, who behaves in a sexually suggestive or lewd manner, often in an immature or inappropriate way. It can be used to criticize someone for being overly focused on sexual topics or for behaving in a manner considered vulgar or indecent.
