The method for determining the identity of a target based on a process of elimination. The term is often applied for humorous effect meant to indicate that a solution can easily be found by simply eliminating the obvious non-solutions.

The concept is based on the animated TV show "Scooby Doo" in which teenage investigators solve mysteries. The typical episode format includes someone dressed as a monster terrorizing people. The "meddling kids" proceed to determine the identity of the person behind the mask, providing an opportunity for the audience to guess who it is as well.

As an over-simplification, you know the person behind the mask simply because he’s the only person in the episode who isn’t Fred, Daphne, Velma, Shaggy, or Scooby (the primary characters).
Brilliant, you just reinvented the Scooby Doo Algorithm to choose what to eat for breakfast. . . It's not that hard since you only have one box of cereal, half a pizza, and ten cases of beer in the house.

An awful rip-off produced by Dj Kass of the original Big Shaq "Man's not hot" song, spread in all Latin America like a cancerous tumor.

A side effect of the exposition to this song (if you're stupid enough) is the loss of a considerable amount of neuronal cells, driving you to a primitive state of cognitive thinking, or making you move in violent contractions of the muscles (known as perreo). Or simply degenerate all your integrity as a person.
Brayan: ¡Scooby Doo pa pa! Y el bumbumbum
David: Oh ¿estás escuchando a Big Shaq? A mi tambien me gusta ese meme
Brayan: Bic ke? :v no we, ando escuchando ente rolonón nuevo, mira nada mas escucha sta prron
David: Mejor no, oye esperate ni te me acerques... ¡¿Pero que haces?! No esperate! AYUDAAA-

(Al día siguiente David despertó en medio de un callejón, dandose cuenta de que se habían llevado su cartera, su virginidad y su dignidad).
