The racial slur of the day is Frog.

It is used to refer to French.

Deep lore: The French are said to laugh like frogs. When they laugh, their adam's apples bulge out of their necks like frogs. Also perhaps from the French delicacy of frog-legs. Another possible derivation is the Fleur-de-Lys displayed on the French king's banner in the Middle Ages, which, to the English enemy, looked like squatting frogs. UK origins.
