How old is the term "adorkable"? It goes at least as far back as 2004. But I'd have to say that one of the guys who defined the term was Seth Green (38 Wednesday). Wow, has it really been 14 years since he was on Buffy the Vampire Slayer? Yep, it has. And I can't believe he's nearly 40. He looks and acts like someone half his age. Considering all the stuff he's doing, he certainly has the energy of someone half his age. And at 5'4", he's another example that good things come in small packages.
