BTS joined James Corden for the segment of “Carpool Karaoke” on February 26 KST, a month after they made a special appearance on The Late Late Show with James Corden to perform “Black Swan.”  The members jammed out to their new title track “ON” as well as some other fun tunes like “Finesse (Remix) (feat. Cardi B)” by Bruno Mars and “Circles” by Post Malone.

James Corden asked what the members’ nicknames were and stated that he heard that Jimin‘s was ‘mochi’. Corden proceeded to claim that he loved a mochi, in which Jimin replied, “You papa mochi!”

He later asks which members would fight the most, in which the members choose ‘Vmin’ (V and Jimin). After hearing that they would fight about dumplings, he comments, “Not my little mochi,” causing the members’ to crack up.

This cute little interaction between Jimin and Corden blew up on Twitter and social media after the show was over.

‘Papa mochi’ even began trending all over after the show as well!
