Bunch of Brian Baldingers
Em is calling all of his haters mere spectators/commentators when it comes to his image and music..
“Ball dinger” is also slang a homosexual, or ball-licker which is exactly what he says in the next line.
This is also a continuation of the Football analogy started about 4 lines before, also of the buttkissing with the ball-handling (ball dingers) wordplay.
