Guitarded

Someone who has no real skill or experience on guitar, yet insists on creating typically unmelodic noise, usually in the form of repeatedly playing the same scale over and over, ad infinitum.

House guest: "What is that noise?"
Host: "Oh. That's my dumb-assed guitarded neighbor with his Fender Strat."

Paleodolia

Seeing paleolithic or other prehistoric creatures (dinosaurs) embodied in rocks. Similar to pariadolia, but rather that seeing only a face in the object, one sees the head of some archaic creature.

Elron thought he was looking at perhaps the skull of a dinosaur, but Hyman said it was just a rock and that it was a case of paleodolia, to which Elron replied, "I sure hope penicilin works."
