Honk Honk is a slogan associated with ‘Clown World’ memes on 4Chan and Reddit used to convey absurdist nihilism. Honk Honk’s initials ‘HH’ are a common code for Heil Hitler and it is a common catchphrase of Honkler, a nihilist clown-themed version of Pepe that espouses extreme bigotry.

In early 2022 Honk Honk became strongly associated with Canada’s “Freedom Convoy”, a convoy of anti-vaccine and anti-government activists that used vehicle horns as a symbol of their eventual occupation of Ottawa. Its resurgence was due to both the widespread use of car and truck horns as a protest tool, and by a concentrated effort from white supremacists involved in the convoy. Most individuals sharing Convoy memes that include "Honk Honk" do not mean to express support for Hitler, but there are those that do, and the memes being shared by those that don’t utilize imagery and vocabulary associated earlier, bigoted expressions.
