Kris Kross was a teenage rap duo from Atlanta comprising Chris “Mac Daddy” Kelly and Chris “Daddy Mac” Smith. They are best known for their hit “Jump”, which was #1 on the Billboard Hot 100 for 8 weeks. It’s a song from their first album “Totally Krossed Out”.
Their fashion styling helped them to become popular, they were wearing their clothes backwards… and of course I tried it too and stopped the first time I went to the toilet 
Kris Kross made us JUMP ! 19 years ago… in 1992. Here’s the videoclip :
