4minute's upcoming track "Is It Poppin?" has been deemed unfit for broadcast by KBS.

Apparently, the network had a problem with the English word "ass" in the song's lyrics. "Is It Poppin?", by Brave Brothers, is a hip hop dance track about a girl who's upset with her boyfriend who loves to party.

4minute will be removing "ass" from the lyrics in order to re-submit the song for review.

Check out the MV teaser for the song that's causing all the fuss up top, and stay tuned for its release on the 28th!
