So here we go again, with the same old story. 1. An expression used when something is about to begin or arrive. Here we go, another one of Grandpa's boring stories! A: "When are the fireworks going to start? We've been waiting here for over an hour!" B: "Here we go, the first one just went off." 2. Said when something or someone has been found or identified. Let me just see if I can find that in the library database… here we go, the complete works of William Shakespeare.

Hello Law.Robinson. ''here we go'' is used when a person is ready to begin something that takes skill, courage or luck. For example: ''Here we go!", she murmured and jumped out of the plane. There's also ''here we go (again)'', used when something bad starts happening again. For example a parent enters a child's room and starts to scold him/her again, and a child says: ''Oh, here we go!'' ''here we go'' is also often sung repeatedly by English football crowds when their team is successful. Here's the link https://www.youtube.com/watch?v=Hl9fpAMP1lE I hope this helps :)
