Equinep

Meowrails, or Equinep, is the het ship between Equius Zahhak and Nepeta Leijon from the Homestuck fandom.

Canon
Nepeta and Equius are canonically in a moiraillegiance, a form of troll romance. They are the first example of a moiraillegiance seen in the comic. Nepeta often takes a more playful stand to their interactions and does not take Equius very seriously, while he attempts to be stoic and controlling, resulting in them quarreling. However, it is clear that they care about each other and appreciate each other's quirks. When they meet on LOLCAT, Nepeta tackle-hugs Equius almost immediately upon seeing him. In [S] Equius: Seek the highb100d, they have a character roleplay session; although Equius does not fully understand the concept, he is willing to indulge Nepeta's interests. After this, Nepeta gives him her hat to wear.

Fanon
Meowrails is an almost universally accepted ship among the Homestuck fandom. Due to moiraillegiance more closely resembling a typical human friendship than a romance, they are often shipped as a friendship rather than a het ship. In most human AUs, Equius is portrayed as Nepeta's best friend.
