You need to complete the two dancing mini games, one at Maisonette 9 and the other at Hercules. The first one you encounter will involve moving the & in various directions in time to the music. At points you will also need to hold the sticks and use the & to complete certain moves. You will know if you are doing it right as the girl should get closer to Luis.
Doing this fast enough will bring on the second mini game where you see Luis and a group of people doing the Bus stop dance. Do this in both clubs and the achievement should pop up.
