for example:
- I'm warning you, don't go to him!
- I am going to him, do me something!
is there such saying? I can't find on google examples to this.

also: "I got on it". "I got on him".
when somebody try to hide something from you and you "get on it" - discovering it.
is there such saying? I can't find on google examples to this.

thank you very much
