Humbug!
 

I am very much in favor of bringing back humbug, however I find that many people fail to grasp the meaning of the word fully before employing it.

For those who need to know, "humbug" is a synonym for "bullsh*t" or "nonsense". It is not a simple amplifier like "dammit". In other words, if you find this post to be of little merit, you might say "This post is humbug!" you would not say "This post is nonsense, humbug!"
