Spider-Man is a fictional Marvel Comics superhero. One of his abilities is to react to danger quickly with his "spider-sense."
Major John Sheppard referred to the instinct he has as a "spidey-sense", in reference to Spider-Man, and also jokingly labelled Sgt. Bates' distrust of Teyla Emmagan with this name, because of Bates' lack of proof. (SGA: "Suspicion", "Submersion", "Harmony")
