What are some seemingly innocent but really BAD pet names?

Well, years and years ago, my neighbor had a little black-furred mutt.

Wanna guess its name? It rhymes with bigger.

Now, you wanna hear the hilarious part? My neighbor was African American. She named it that because, "ain't like white folk don't call black dogs that, at least she'll know to come when someone says it, and she can bite their ass."

Miss Margaret was awesome.
