Ça bouge in french means: it moves, it rocks, its great, something like this.
French speaking citizens in Brussels use it to express their joy for something that they like, usually a party, an event, a festival.
Discovering whats going on in Brussels every Summer was a big surprise for me!
Every Summer the city transforms to a big party with a lot of stages with many different kind of musics! Me I prefer the ones with the House, Electro ones!
Because the city is quiet small, you know almost everyone by name! Mouth by mouth you know where is the next place you definitely need to be!
Flirting is the easiest thing to do and the most common phrase you hear is "where are you from, what is your name".
