I love these guys. I've been watching them for a while. They are called Les Twins. One of the things that dancers can take away from these young men is that they developed a style from a certain genre...their choreography is smart, witty, full of humor and tons of technique....it looks absolutely effortless on their part. Go to YOUTUBE and check out their videos from various competitions and showcases.
And practice, practice, practice...rehearse, rehearse, rehearse!
