you had one job 

Response to failing to do the one and only thing you had to do. This is told, either in a disgusted, mocking, or angry tone to people, animals, inanimate objects, and anything else that fails to complete the simple task for which it was designed.
A way to express total fail, epic fail, especially when the one job was very simple.

To a cheap park bench that broke while I was sitting on it, "You had one job, park bench!"
To an accountant who was fired for inaccurate computing of business records. "You are supposed to be an accountant, right? You had one job, Sandy."
To a friend about my broken down car, "Damnit, it had one job!"

Someone that keeps it true to whomever they keeping around,

I'm not the one 

Don't funk with me. You are biting off more than you can chew. I'm more than just talk. You are starting a fight with the wrong person. "I'm not the one"

"I'll beat your A$$"
"I'm not the one"
