Scrooge's grumpy cry (3)

I believe the answer is:

bah

(Other definitions for bah that I've seen before include "Exclamation of contempt or disgust - Scrooge used to say it" , "Exclamation of disgust or annoyance" , "Appalling!" , "Comic expression of contempt" , "Disbelieving expression" .)

I've seen this clue in The Washington Post.
