A meaningless acronym which most often stands for "Oh My God What The Fuck Barbeque." It most likely originated on Something Awful (somethingawful.com). It can be interpreted simply as
gibberish, or used when one wants to emphasize one's own incoherence, lack of understanding, or to
mock others.
It usually has an air of mockery, specifically with regard to teenagers who a lot of use
three-letter acronyms.
