Every pending beatmap has a hype train that roughly represents how many people are interested in seeing the map ranked. s can post special beatmap discussions in the General (All difficulties) tab with the Hype! option to contribute to a map's hype train. xlx
Beatmaps need at least 5 hype (one complete bar of the hype train) to be eligible for nomination, a step towards getting the map ranked.
s start with 10 hypes, and they are consumed when used on beatmaps. Each hype takes a week to become available again.
