Finn, for one, is a reference to the character Finn from the popular animated television series Adventure Time. He is a human boy who lives in the post-apocalyptic Land of Ooo with his best friend Jake, a magical dog. Finn is brave and adventurous, and is often seen fighting evil forces and protecting the citizens of Ooo. The term LAD, which is a three letter acronym, stands for 'Loyal Adventurer and Defender, ' which is a fitting description of Finn's role in the show.
