B2K was an American boy band that gained prominence in the early 2000s. Comprised of members Omarion, Raz-B, Lil' Fizz, and J-Boog, the group was best known for their R&B and hip-hop influences, producing hits such as "Bump, Bump, Bump" and "Uh Huh." Omarion's smooth lead vocals and the group's choreographed dance routines were distinctive elements contributing to their popularity. Although their active period was brief, from 2000 to 2004, B2K made a significant impact on the early 21st-century teen music scene, particularly among young urban audiences.
