Help the food critic finish their dramatic review of a new restaurant by choosing the correct word.

I have eaten some terrible meals in my life, but this glowing green soup is absolutely the _____ thing I have ever tasted!

The correct answer is worst.

The adjective "bad" is irregular. Its comparative form is "worse" and its superlative form is "worst." We never use "baddest" or "most bad" in standard English!
