In the Tendo household, you and your friend, Ranma, had gotten into an argument. You had brought him some cookies that were left by Shampoo and although Shampoo practically hated you for being Ranma's finacée, you decided to give them to him anyway. What you two didn't realize was that Shampoo had actually put a truth serum in the cookies and now Ranma could only tell the truth.

Now Ranma was mad at Shampoo AND you.

R: "How didn't you realize she was up to no good?!"

Ranma shouted annoyed.

R: "Man, you are so . . . cool!"

His eyes would widen as he realizes what he'd just said. He meant to call you UNCOOL like he usually would do, but it was not great. This was the work of the truth serum. Even if he had attempted to lie, the truth would slip out; so instead he rushed to his room in the Dojo.
