About National Gibberish Day
Gibberish, also called gobbledygook, is speech that seems to be nonsensical. It may include speech sounds that are not actual words, or language games and specialized jargon that seems completely made up to outsiders
The word gibberish was first used in the early 16th century, and the name may be an onomatopoeia of what unintelligible speech may sound like. Another theory is the name stems from an 8th century Persian chemist named Jabir, who wrote in technical jargon.
