UGK (short for Underground
Kingz) are a hip-hop duo born and raised in
Port Arthur, Texas. Formed in 1987, by long-time friends Chad "Pimp C" Butler and Bernard "Bun B" Freeman, they are highly respected by many of their peers, due in part to their longevity and their entrenchment in
hip-hop's underground. They also invented the word, "Trill."
