A combination of the words dork and adorable. An overly
intellectual person who is nerdy, dorky and a bit geeky but in an adorable and endearing way that becomes desirable. It's meant to be a compliment.
General examples from tv would be the character's 'Ross' from "Friends", 'Jim' from "The Office", and for obvious reasons 'Chuck'. It is Steve Jobs, Conan O'Brien, Chuck Klosterman,
Malcolm Gladwell, and
Rachel Maddow. John Cusack in an 80's movie. An extreme example is Woody Allen depending on how old he was when he starred in the film you are watching.
The ratio of adorkability rises when said nerd/geek becomes successful in business and switches from glasses to contact lenses.
"Did you see when Ross proposed to Rachel
last night on "Friends"? He is so adorkable!"
"That girl
over there with her hair up in a scrunchy,
drinking her double mocha non fat latte and doing the NY Times crossword puzzle..is so adorkable."
