all up in my grill 

whoever the person is below me is wrong.
all up in my grill doesn't necessarily mean in someone's business.

it means someones in your face.
grill = face.

therefore, it can also be used describing someone who is excessively annoying and bothering you.

That ho was all up in my grill. Tell him to get his nasty, annoying self outta my face.
