The clip in question comes from the recent episode with Park Ji Sung and Patrice Evra. While watching the game from the bleachers above, Sulli can be heard quietly saying around the 63 minute mark, "cao ni ma", a phrase similar to "you m*therf*cker" in English.

"While discussing the Chinese language with the staff members, the topic turned to Chinese curse words," SM Entertainment explained. "We think that the words accidentally came out on broadcast without being edited."

SBS expressed their regret at the situation. "Apparently, the words came through while she was cracking a few jokes," they said. "In any case, the editing mistake is a failure on our part, and we will edit this out in the online streaming version. We will be careful in the future to make sure something like this doesn't happen again."
