In the song, Pimp C raps about Houston's current status.

Houston hip hop artists Lil' Flip, Slim Thug, & Z-Ro are also mentioned. He also talked about how Paul Wall & Chamillionaire breaking up and going separate ways. Moreover, he raps about Lil Keke and his new album with Swishahouse. The video is given a Godfather theme. The video was not as popular as videos for songs like 'Pourin' Up', mainly because there are several displays of graphic violence. However, it was nominated for Best Video at the 2007 Ozone Magazine Awards.[2]
