Gay football player on glee

David "Dave" Karofsky, or simply known as Karofsky, is a recurring character on Glee. He was a student at William McKinley High School who, along with his friend Azimio Adams and other football team members, used to constantly bully the kids in Glee Club, especially Kurt.
Karofsky is revealed to be gay early in that season. He is closeted and remains so at the end of the season, though he has stopped bullying and has won the election for Junior Prom King.
