In the modern era, "flaming" was used at East Coast engineering schools in the United States as a present participle in a crude expression to describe an irascible individual and by extension to such individuals on the earliest Internet chat rooms and message boards. Internet flaming was mostly observed in Usenet newsgroups although it was known to occur in the WWIVnet and FidoNet computer networks as well. It was subsequently used in other parts of speech with much the same meaning.
