"Slam" is the second single released from Onyx's debut album, Bacdafucup. Released on May 11, 1993, "Slam" was Onyx's breakthrough single, making it to number 4 on the US Billboard 100 and was the group's second straight single to make it to number 1 on the Rap charts. The main chant of the song's chorus is a variation of the vocal and organ intro to the much-sampled instrumental "The Champ" by The Mohawks, and is also noted for its heavy use of Christmas bells that were a staple of many hip-hop and R&B songs at the time of its release.
