Kabukimono

The "kabuki-mono" were a group that dressed in a somewhat strange, peculiar style and spoke in a vulgar, specialized vernacular which matched their often outrageous behavior. 
They were masterless or wandering samurai or ronin, or men who had once worked for samurai families who, during times of peace, formed gangs.

It is also said that Izumo no Okuni borrowed heavily from the style and the personality of the kabukimono when she first started performing in Kyoto, which eventually led to the creation of the classical Kabuki theatrical form.

Kabukimono were often very violent and rude, doing things such as not paying at restaurants and stealing money from townsfolk. Cases of cutting down people simply to try a new sword, or large incidents of violence were common in areas where kabukimono could be found, in large cities such as Edo and Kyoto. Wrestling or dancing in the streets were also common. The peak of kabukimono activity was during the Keichō period (1596–1615), although also during that time, the bakufu (shogunate) became more strict, and the kabukimono faded away.^[2]
