Rumours can be so much fun when people don't take it too far.
I love starting rumours, they're my favourite way of seeing how much I can make people believe. My favourite ones were about teachers in high school.
I also like pairing people up in promiscuous situations especially when they would never have considered each other.
I also love having rumours spread about me, I generally play along. Even when they're ridiculous or outrageous. Because people believe what I say and it brings me pleasure.
