"RBB (Really Bad Boy)" is a song recorded by South Korean girl group Red Velvet for their fifth Korean (eighth overall) extended play RBB (2018). Written by SM Entertainment songwriter Kenzie and Sara Forsberg with production by Timothy 'Bos' Bullock and MZMC, "RBB (Really Bad Boy)" is primarily an "addictive" R&B and dance-pop song with influence from jazz and hip hop, with the lyrics expressing the charm of a "bad boy".[6][7] It was released as the lead single from its eponymous extended play on November 30, 2018, by SM Entertainment and Iriver Inc as the distributor, along with an accompanying horror-themed music video.
Upon its release, "RBB" received mixed to positive reviews from music critics who deemed it "controversial" and "unfamiliar" to the public.[citation needed] The song however, gained compliments for its "unapologetic" boldness thanks to the group's experimental path. Domestically, it achieved moderate success in its native country, becoming their eleventh top-ten entry on Gaon Digital Chart, while being a bigger success outside of their native country, peaking at number one on Billboard's World Digital Song Sales.
