Scottish: mockery, ridicule, or a deceptive trick; the action of mocking or deceiving.
From Scots 'brok' (to mock or cheat) + -ery (suffix indicating action or state). Ultimately from Old Norse or Germanic roots meaning to deceive.
Broquery is exactly the kind of specific insult-word that regional languages preserved—it's not just 'mockery' but the whole behavior and attitude of someone who tricks and ridicules others.
