apathetic threshold

The point at which things become so inane or dramatic that you stop caring.

Bill: DON'T YOU EVEN CARE WHAT I'M SAYING TO YOU? THIS GAME IS MY LIFE!!!
John: No. I reached my apathetic threshold when you bitched about being killed for the sixteenth time.

Edwin: I reached my apathetic threshold when she broke up with me; as if I didn't see that one coming!
Scott: I do say, my good sir! -sips tea-
