On pg.13, he calls himself "KimTaku" who is Kimura Takuya, a famous leading man actor. He shares the same first name with (Takuya) with Numakawa.
Option 2 in the poll on this page mentions Dali. Salvador Dalí, artist with a very fancy moustache.
pg.14, the poll options are:
1. Numaccho (just a cool name that rolls off the tongue I'm guessing)
2. Numa-Rin (cutesy girl suffix)
3. Numa-tan (-chan, but infantalized because kids have a hard time saying the ch- sound and it caught on)
4. Numabukuro (a play on the area of Ikebukuro in Tokyo, the the kanji for numa 沼 and ike 池 are sort of similar but not really)
5. NUMALION (ヌマライオン)
6. Bessho Takuya (別所 拓也, play on Bessho Tetsuya; actor, host)
pg.15, Miyamoto says that it's "ohmigod". The jp text has him saying that it's やべぇ、これ.
"Yabai" is a strange word which can mean either good or bad, and exist in both positive and negative contextual use at the same time. Something that can be "cool" and "horrible" simultaneously. "Impressive" yet "gross". Miyamoto is both having fun but cringing at the same time.
A status update:
We are now halfway caught up (newest chapter 142 came out yesterday). This also might be a good time to inform everyone....the title is actually "1 day outing diary Foreman"
1日外出 - 1 day outing
録 - diary, record, anthology, chronicles
ハンチョウ - hanchour/foreman
That's why a lot of these chapters start with "X day, X location...on this day the three of them..."
is it too late to change it now that everyone's already used to it? haha
Anyway, new volume starts here and imho the really fun chapters start here in the corona era
