Jumpstyle
Jumpstyle is an electronic dance style and music genre popular in Eastern Europe, as well as certain parts of Australia and the United States.
Jumpstyling is often referred to as "Jumpen": a combination of the English word 'Jump' and the Dutch & German suffix '-en' (meaning "to jump" or "jumping").
It originated in 1997 in Belgium but gathered bigger popularity in their neighboring country the Netherlands in the 2000s.
