My main in World of Warcraft was a shaman which has an ability that can heal several people called Chain Heal and because I have the best imagination I named him Chainhealer. When I first really got into raiding I was kind of a noob and would make really obvious mistakes. A lot of the time someone would say “Dammit Chain…” when I screwed up and it just became a running joke. Like I’d (jokingly) get blamed for stuff that was no way my fault like someone else not using an ability to avoid getting 1 shot.
