Unquote

[Tanya Shivari]

An incorrect way of saying endquote.
A popular mistake is to use the term [quote unquote]. This term is short form, and originated from using the word quote before [quoting] someone, and the word endquote at the end, to signalize that you are done quoting.
Nowadays, the phrase quote unquote is [being used] as a whole before quoting something.
