What's your "secret single behavior"?

In the TV show Sex and the City, one episode focuses on the topic of “secret single behavior” (or SSB). They define this as things you enjoy doing when by yourself, but that you would never do in front of a girlfriend or boyfriend.

For example, Charlotte said that she liked to stare at her pores in a magnifying mirror for at least an hour every day, Carrie liked to snack in the nude, and Miranda liked to put moisturizer on her hands, put on cosmetic gloves, and watch infomercials.

So, ‘fess up – what’s your SSB? Me, I dance like a moronic fool.. I could never in a million years let loose like that with someone else around. :)
