the.com/jingoism

Patriotism that's been drinking and wants to fight someone outside.

means Aggressive, chest-thumping nationalism that pushes for war or hostility toward other countries, dressed up as patriotic pride.

from Comes from the phrase 'by jingo,' a minced oath (a polite stand-in for something stronger, like swearing 'by Jesus' without quite saying it) that was already floating around English speech. It got politicized in an 1870s British music-hall song supporting war against Russia, with the chorus boasting 'we don't want to fight, but by jingo if we do...' The crowd-pleasing bluster of that song gave the critics of such attitudes a ready-made label, and 'jingoism' stuck as the word for patriotism spoiling for a fight.
