YUP (Yhdistyneet Urbaanit Puoskarit, originally Y.U.P. Young Urban Perverts) is a finnishrock-music group. The band arose amongst three students of the Savonlinna senior high of arts in 1987 and played some rather primitive, progressive hard-core punk with English lyrics. Originally the group consisted of Jarkko Martikainen (guitar), Valtteri Tynkkynen (bass guitar) and Jussi Hyyrynen (drums). With the EP Turpasauna in 1990 the language changed into Finnish and the music became more complicated.
