The Kurbaskanks (+ friends) are a group of people who came together to enjoy the fictional non-canon (ouch) relationship of Kurt Hummel and Sebastian Smythe from the TV show Glee.
It started out with around 8 people, as time went by it grew to a current number of (more or less) 50 people.
Grant Gustin himself - who portrays Sebastian Smythe - agreed to be the King of the Skanks.
Person 1: Oh look, those people gossiping about Kurtbastian. I bet they're Kurbaskanks.
Person 2: Yeah, wow, they must be nailing it.
