Pulling a duff

When an artist releases a Greatest Hits album after very few releases in an effort to make money.

This comes from when Hilary Duff released a Greatest Hits album after only releasing two albums.

Guy:"Dude Band-x is soooo pulling a duff on us."
Guy2:" man, that sucks"

Hilary Duff

A girl who makes a good living, and at least tries in her career instead of bashing people and/or bands on the internet all day.

Her voice isn't great, but her acting is decent.

At least Hilary Duff has a life.
