A: Why didn’t you say anything after John gave his opinion at the meeting?

B: I was shocked. What he proposed didn’t pass the laugh test.

Note: This saying, first used in the legal circle in the 1980s, suggests that something is so irrational and nonsensical that it will probably be laughed at by anyone who hears it. People also use “the giggle test.” It’s a mild way to say something “is a stupid idea.”
