Nattō is associated with both health/wellness food culture, which as we all know has fascistic roots and is associated with ideas of purity and national strength.
Further reenforcing this is that Nattō is considered a food only Japanese people like, a pillar (albiet a minor one) of ethnonational identity. Consider: 30% of people who eat it do not enjoy it but instead eat it based on aformentioned health reasons[1]. Offering nattō to people in order to see their repulsed reactions is an act of humiliation, reenforcing the superiority of the Japanese character and identifying an out-group.
Anyway it’s ok, a little mild. More stale coffee than cheese, I keep craving it though and am now fermenting my own


Peanuts?
They’re a southern US thing. Honestly sounds like an accidental fermentation-involved incident away from a 'Murican version of nattō, seeing as how both are in the legume family.
…Oh fuck me, of course that exists already
The repressed homoerotic urge to fill your mouth with slimey nut.
