What does flamer mean?
A flamer is someone who posts deliberately offensive, abusive, or provocative messages in online spaces such as forums, chat rooms, and comment sections. The word derives from 'flaming', the practice of launching hostile written attacks, and it emerged alongside early internet culture, where entire disputes between users became known as flame wars. As a term, it is informal and almost always pejorative: calling someone a flamer accuses them of trolling-like behaviour intended to inflame rather than discuss. A separate, less common technical use refers to a component that produces or regulates a flame in burners and heating equipment. Understanding 'flamer' offers a window into how language evolves with technology — a vocabulary born from the earliest days of online argument, before 'troll' largely displaced it in everyday speech.
A person who sends or posts deliberately inflammatory, abusive, or provocative messages, especially online.
"Moderators removed the flamer's posts and suspended his account."
Informal register, primarily internet-culture vocabulary; strongly negative connotation.
A device or part of a burner that produces or directs a flame.
"He cleaned the furnace's flamer before relighting it."
Technical/engineering context; far less common than the internet-culture sense.
Standard pluralization applies; used when referring to multiple offenders in online moderation contexts.
"The moderators coordinated to ban the flamers from every board."
Before 'troll' took over the internet's vocabulary, the people lighting up message boards with insults were known as flamers — and their battles were called flame wars.

Etymology of flamer
Flamer is formed from 'flame', a word inherited through Old French 'flamme' from Latin 'flamma', meaning blaze or fire. The extended figurative use of 'flame' to describe passionate or angry communication developed in English over centuries, giving rise to 'inflammatory' rhetoric. The specific noun 'flamer' — denoting a person who launches hostile online messages — arose in late twentieth-century internet communities, particularly on Usenet and early bulletin boards, as users coined terms for the antisocial behaviour they encountered. Its sibling term 'flaming' and the phrase 'flame war' come from the same digital-era coinage.
