Relationship Overview Edit
Hiccup and Snotlout grew up together, though they were never very close. Snotlout was under considerable pressure from his father to be as manly and tough as he possibly could; in consequence, he often bullied Hiccup to show off how masculine he was in comparison to the chieftain's son. This behavior continued even after the two became part of Berk's dragon-riding team, though eventually they bonded enough to maintain a tentative friendship.
Those who support this pairing think that Snotlout could have had feelings for Hiccup for a long time, but tried to hide them by ridiculing the other boy. His consummate flirtation with the girls of the tribe could also be an attempt to hide his orientation by being as manly as possible. Any possible reciprocation from Hiccup would only come about if Snotlout were to admit his feelings and apologizing for his bullying.
By-and-large, those who ship these two use only the versions of the characters from the movies because there is no explicit familial relationship between them, whereas Hiccup and Snotlout are cousins in the book series.
