a humbug - When you’re so disappointed you want to scream, throw a pill

When you’re so disappointed you want to scream, throw a pillow, and maybe eat a whole cake in one sitting.

I got a C on my science test. I did the humbug dance in my bedroom and screamed at my textbook.

My friend said I was going to win the spelling bee. I didn’t. I did the humbug dance in the hallway.

My dog ate my math homework. I did the humbug dance in front of the whole class.
