here we go

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." Here we go, the baggage carousel is finally moving. Look for your suitcase!

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. Here we go! Yep, Mom's recipe book was all the way in the back, just like you said. Here we go, now we're getting somewhere. Our security camera caught the robbers as they were running away!

3. A chant used by fans in a football (soccer) audience to show support for their team, especially after a successful play. Primarily heard in UK. The tremendous roar of "Here we go, here we go, here we go" had become completely deafening after the goal. Well, of course the fans aren't going to chant "here we go" now, as their team falls further and further behind. The opposing coach's instructions to his players were drowned out by "here we go" chants.
