Duff

I used to really like this name but thanks to a recent movie, a kid would be known as a designated ugly fat friend. So frustrating.

It's a last name, and it doesn't sound very flattering. It has unfortunate associations with Duff beer from the Simpsons and pop singer Hilary Duff. Please avoid this name.

Duff Beer from the Simpsons and Hilary Duff come to mind, which can't be good. Can't be, and isn't. The name sounds a bit fluffy and child-like anyway.
