Destiheller is a pejorative term coined to describe those viewed as extreme fans of Destiel. It has been reclaimed to some extent by Destiel fans themselves in February 2014 as a badge of honor. The term is a portmanteau of Destieler (one who ships Dean and Castiel as their OTP) and Hell, and has come to be a play on the fact that Destiel is a "match made in hell," literally, as Castiel raised Dean from hell. The image frequently adopted by Destihellers is one of pirates (a "rogue ship") or a motorcycle gang.
On Tumblr, "Hate Tags" are employed by fans disgruntled with ships, characters and celebrities. Ostensibly these are to act as a content warning, allowing fans avoiding negativity to bypass the hate, but they have become fandoms of their own dedicated to hating the object of their ire more than sharing any unified ideology. "Destiew" is one such Hatedom, and is responsible for coining these and many other terms within the shipping wars. Destiew is a portmanteau of Destiel and ew, the informal expression of disgust or disdain.
Destihellers became a popular term for the "pirates" of the USS Destiel, following what many fans took as negative commentary about Destiel during Jus In Bello Italy 2014 by Jensen and Jared. While some on both sides of the fandom divide took their commentary to mean Destiel would never be made canon, others decided that canon or not they would continue to enjoy their ship in fandom and interpret the subtext within the show. Declaring themselves a "rogue ship," Destihellers trended USSDestiel on Twitter and spread it to Tumblr, encouraging Destiel fans to continue enjoyment of their ship regardless of negative perceptions.

Anti-Destiel fans equating Destiel to a fandom disease ranging from Cancer to Ebola to Herpes has been a long-standing insult, but in January 2015 anti-Destiel fans coined the term "Destilence," a portmanteau of Destiel and Pestilence. Continuing the trend of re-appropriating negative terminology humorously, Destiel fans embraced and then lampooned this term, discussing the signs and symptoms of Destiel and warning signals that you might be "infected." Unfortunately (or fortunately, depending on your side of the shipping wars), Destiel fans "like the disease."
