"Supa Ugly" was a 2002 mixtape diss track from the rapper Jay-Z during the Nas/Jay-Z beef. The track was not featured on any of Jay's LPs and was in response to Nas' diss track "Ether". The first verse of the song is delivered over a sample of Nas' "Got Urself a Gun" beat. In this verse, Jay-Z dismisses the "Ether" track as being filled with falsehoods and questions Nas' street credibility. The beat of the song then switches up to Dr. Dre's "Bad Intentions". In the second verse, Jay-Z goes into detail about his alleged affair with Nas' baby's mother, Carmen Bryan, and mocks Nas' relationship with her. Nas responded to this track simply by declaring that he and Carmen were split up during the time of Jay-Z's alleged affair.
After hearing the song on the radio, Jay-Z's mother Gloria Carter demanded Jay-Z publicly apologize to Nas and his family, to which Jay-Z obliged. In a future interview with Rolling Stone, Jay-Z claimed that mentioning his relationship with Bryan was fair game because in "Ether" Nas had called him a faggot and used the phrase "dick-sucking lips" to describe what he viewed as Jay-Z's exploitation of The Notorious B.I.G.'s memory, as well as using anti-gay slurs multiple times in the diss. In "Supa Ugly," Jay-Z flips this type of language around on Nas, rapping, "And since you infatuated with sayin' that gay shit/Yes, you was kissin' my dick when you was kissin' that bitch." Jay-Z had vaguely referred to the affair in "Takeover," rapping, "...you-know-who did you-know-what with you-know-who/Just keep that between me and you."
Most true hip-hop fans still think Nas won the battle.
