What does 'kick in the door' mean?
is this a slang expression?
and I have another question.
"I got it full control" means "I could control it fully'?
Unless context indicates otherwise, I have to believe that "Kick in the door" is meant literally.
As for the other one, it is, I think, "I have it under control" or "I have it fully under control" and that is also meant literally.
