Mappers term from game called "osu!". Harshly curved sliders also known as the 'butt sliders' is one of the terminologies that'd been used by only the most ancient mappers from the very early years on where bezier curves were the standards.
In it's glorious days, that type of mapping technique/sliderart was primarily being used to satisfy
a certain group of people and to secretly boost the map's reputation/popularity by small but impactful percentage. It was mesmerizing to see how that sparkling beauty had conquered the erotic sides of those still innocent circle gamers. Nowadays that kind of technique is only rarely being seen and it's terminology only appears to be used by a very small clan of furrious mappers,
mainly being rejected duo it's aesthetics seeming to be too 'ugly'. However, these types of sliders could make a huge comeback in the future as when they appear in a group of two they can perfectly illustrate a female's bust size of at least '2', along with having a humongous potential in revolutionizing the anime mapping meta as the general usage of double ds much skin backgrounds had been denied by the big leaders.
