The use of the word frog to mean “a French person” is a slur that arose because the French were stereotypically thought of as eating frogs.

Explanation

A frog is a small amphibian with long back legs that allow it to hop. Most frogs have fat little bodies and bulging eyes on top of their heads. You'll often find frogs near fresh water lakes and ponds, since they lay their eggs in the water. Perhaps the most famous literary frog is the one from the German fairy tale "The Frog Prince," in which a princess's kiss transforms a frog back into the prince he once was. Frog is also a very rude informal term for a person from France.
