Triple parentheses or triple brackets, or an echo, often referred to in print as an ( ), are an antisemitic symbol that has been used to highlight the names of individuals thought to be Jews, and the names of organizations thought to be owned by Jews. This use of the symbol originated from the alt-right-affiliated, neo-Nazi blog The Right Stuff, whose editors said that the symbol refers to the historic actions of Jews which have caused their surnames to "echo throughout history". The triple parentheses have been adopted as an online stigma by antisemites, neo-Nazis, browsers of the "Politically Incorrect" board on 4chan, and white nationalists to identify individuals of Jewish background as targets for online harassment, such as Jewish political journalists critical of Donald Trump during his 2016 election campaign.
