Snamione

Pairing names are often portmanteaus of characters' names, although fans may not always agree on the forms that these amalgamations take — the Snape/Hermione ship, for example, may be called Snamione, Sevmione, Snermione or Snanger, depending on the preferences of the fans who participate in it.

Therefore, it is logical that the selected trope will more often be used in fics which have a non-normative ship: fandomstats relays that, within the EWE tag, some of the most prolific ships include Drarry, Dramione (Draco/Hermione, not a slash ship but still one that does not conform with Rowling’s normative ideas as it contains Draco, an antagonistic character), and ships involving Snape, including Snamione and Snarry.

And the love bred a shameful number of Snamione fanfics in the coming years.
