What are 'fanfarroons'?

I assume it'sn alternate spelling of fanfaron (link): "A bully; a hector; a swaggerer; an empty boaster". From Fr < Sp fanfarron cf. It fanfano and OSp. fanfa 'swaggering, boasting' and Ar farfār 'talkative'. I've seen quotes from Dryden and Walter Scott.

Ceci n'est pas un seing.
