Jingo simply reminds me of Jingoism.
From Wiki: Jingoism is defined in the Oxford English Dictionary as "extreme patriotism in the form of aggressive foreign policy". In practice, it refers to the advocation of the use of threats or actual force against other countries in order to safeguard what they perceive as their country's national interests, and colloquially to excessive bias in judging one's own country as superior to others â an extreme type of nationalism.
In addition, there are just too many other "brandable" domains out there to justify a $xx,xxx asking price for this one, as catchy as it is. Good luck with it, though!
