When do you do the fist bump ? When I watched The Office, I didn't understand well this phrase by Michael, "I'm not gonna bump." Does Michael mean he is not going to approve or he is not going to do fist bump? Quotes from The Office: Michael admit or implied he has fallen in Koi pond. Michael: It was- Ok. This is what it was. It was these bunch of idiots who had put a fish tank in the ground with no cover and no railing. Angela: So you fell in? Michael: No. Maybe I was trying to save a child that had fallen in. Angela: So a child had fallen in? Michael: Not yet! Kevin: That is hilarious. [extends hand for a fist bump] Michael: No it is- don't! I'm not gonna bump. I'm not gonna bump. And it was not hilarious. It was very, very terrifying. [Stanley laughs] Is it right 'bump' means fist bump and it implies to approve he has fallen?
