Deception or trickery; dishonest or misleading behavior or language.
From 'flag' meaning to decrease in vigor or to show weakness (from Old Norse flag, to flap), combined with the suffix '-ery' meaning practice or behavior. Meaning shifted to deceptive behavior.
This is an older, somewhat archaic word that captures the idea of someone 'flagging' their honesty or letting their truthfulness 'flap away'—it's a colorful way to describe cons and deceptions!
