I wasn't sold on this plan of Catalina's until I realized that Diane and Lucy would totally be into it.
I also like that Catalina believes she's the only one likely to experience the penalty she's suggesting. I imagine that sort of penalty actually could be fun, but it really all depends on the individuals playing and the vibe of the group.
Also, I'm someone who commonly deals with embarrassment by publicly sharing it, so I might be biased.
