Ultracrepidarian

I had just been thinking, considering I'm a useless old PITB, preternaturally shy, even self-loathing, why do I keep tossing comments out as if I think anybody wanted to read mine? What compulsion motivates my manic public displays of my foolishness, ignorance, and social maladjustment?

Then I discover.. I'm ultracrepidarian.

Well, crep!
