I think what you are looking for is "knowing us", but your question is unclear. Do you mean that if someone knew you and your personality and your characteristics (and the other person, since you said "us"), they will know that you will make a lot of 'whoopsies'? For example, let's say I am very clumsy and I trip and fall down all the time. And one day I'm at dinner with high heels on. I can say, to myself, "knowing me, I'm going to fall on my face tonight..."

I'm not sure what you're question is. The phrase you wrote is unfamiliar to me.
