in making of my girl pv

[tangerinesun]

while sho, nino, ohno and jun are playing shiritori (word game say a word which begins with the final syllable of the previous word)

at "16:55"
jun answered "rinda."
so the next answer should start with da-. then sho said something but it was censored.
does anybody have an idea  what sho said?

ahhh according to
g_esquared seems like it's "dappun (脱糞)"  which means bowel movement

yey thank you!
