A What?

If they told you I'm mad, then they lied. I'm odd, but it isn't compulsive. I'm the triolet, bursting with pride; If they told you I'm mad, then they lied. No, it isn't obsessive. Now hide All the spoons or I might get convulsive. If they told you I'm mad then they lied. I'm odd, but it isn't compulsive. What Poetry Form Are You?

I never heard of a triolet before. Via Alicia.
