Mochi is a small Japanese rice cake and can be used to describe someone who is small and cute. To call someone mochi sexy is to say that he/she is both cute and sexy at the same time. The phrase - known in the K-pop community - originated with boy group member Park Jimin, who exudes cuteness and sexiness, sometimes at the same time.
Person A: how can he be this sexy when he was just giggling adorably five seconds ago?
Person B: he's mochi sexy. The best aesthetic.

It implies that someone has soft cheeks. Mochi is used to refer to a cute person.
It is a popular adjective and it's not exclusively a nickname for BTS' Jimin.

Mochi is also a Japanese dessert.
Look how soft his cheeks are! He definitely has mochi cheeks.

A middle age man who became fond of the cute man named park jimin. In 2017, James Corden invited BTS onto his talk show and instantly they became good friends. 3 years later, the long awaited carpool karaoke came with BTS and during the video James Corden calles jimin baby mochi, jimin replied saying you you papa mochi and thus Corden earned THE ICONIC title. Forever and always on his twitter bio, PAPA MOCHI
Omg did you see carpool karaoke with James Corden and BTS?
