Background
On October 1, 2018, IU announced the single through promotional posters on various social media accounts. According to Kakao M, the song was created in part to commemorate ten years since IU debuted.

Composition
"Bbibbi" is a laid-back alt-R&B track with confrontational and introspective lyrics that addresses IU's critics, with her turning around commentary on her image. Particular attention was paid to her delivery, including phrases and words like "yellow C-A-R-D" and "hello stu-P-I-D". "Bbibbi" refers to a pager in Korean, in particular the noise the device makes before people leave a message.

Commercial performance
"Bbibbi" debuted atop the Gaon Digital Chart on the week ending October 13, making it her twentieth number one song in South Korea–the most for any artist.

Music video
The music video, directed by VM Project, was released along with the song and makes prominent use of monochromatic colour schemes. IU performs a choreographed hip hop dance routine with a blank expression on her face, which was called "more cute than menacing" by Caitlin Kelley of Forbes. She also appears in high fashion looks, with Billboard stating that she wears a "Grace Kelly-style scarf".

The video currently has over 230 million views, making it the second most popular Korean music video by a female soloist in 2018.
