"Baby Got Back" (a.k.a. "I Like Big Butts") is a 1992 Ol school hip hop song by Sir Mix-a-Lot. The song famously starts with a discussion between two valley girls (voiced by Katherine Reynolds), with one girl remarking to the other "Oh my God, Becky! Look at her butt! It is so big." At the time of its original release, the song caused controversy with its outspoken and blatantly sexual lyrics about the female anatomy, and the video was briefly banned by MTV. However, it has remained very popular over time.
