Ultras

Ultras are a type of football fan renowned for ultra-fanatical support, occasionally to the point of violence and hateful chants and slogans. They are predominantly followers of football teams, typically in South America, Europe, and north Africa.

The behavioural tendency of ultras groups includes the use of flares (primarily in tifo choreography), vocal support in large groups and the displaying of banners at football stadiums, all of which are designed to create an atmosphere which encourages their own team and intimidates opposing players and supporters. The use of elaborate displays in stadiums often is common, as well.
