Old-timey Slang of the Day

Today's word:

darb: an excellent person or thing. As in, "Ain't that a darb?!" or "She's a darb, Sully, a darb!" or "My new jalopy is a real darb, I tells ya."

This comes up a lot in movies from the 1920s and 1930s. I've also seen it in an old Krazy Kat cartoon from the 1910s. Most recently, I heard it in Sons of the Desert, a great Laurel & Hardy comedy I saw on TCM the other day. I think I heard three different permutations of it in that one.
