Katu (喝), Katsu, or Beat!, is a judgement term for when a combo is completed without the highest possible accuracy on every note. However, Katu can't be achieved if a combo contains a 50 or a miss.
There are two types of Katu which depend on accuracy value of the last hit in combo. The first type is worth 300 base score points, and the second one is worth 100 base score points. The 100-point Katu gives the least amount of HP, and 300-point Katu gives less HP than a Geki.
Katu comes from the Nintendo DS game Elite Beat Agents, which osu!'s gameplay is based on.
