Interesting.

So, I went to the Cest La Vie party. It was... Interesting? Interesting is the best word to describe anything when you're trying to wriggle out of a sticky situation.

"How was the meal?"
"Eh... interesting."

"How was the show?"
"Quite interesting..."

"Do you like me?"
"Well, you've been interesting."

"Do you like my Teletubbies headband?"
"It's... interesting."

Yeaaa. It's evasive and it works with both stupid and clever people. Stupid people will simply take it as an answer, no questions asked, and clever people will know better than to probe because they understand you're being evasive for a purpose.
