I wanna know about two things, I know that the first is an idiom and I don't know about the second.
1) rock the boat.
I wanna know what does it mean and where can I use it?
2) true colors
Is it an idiom, and if not what is it and what does it mean?
Did you mean hello thre and I would like to know? Probably.
Rock the boat - stir things up, quetion the status quo, do not follow the flow
True colors - real intentions
