> To place one’s mouth against the side of a dish and push food in with the chopsticks.
I've seen people eat noodles and broth (e.g., ramen) like that a million times? What am I missing? How do you properly eat noodles and broth?
Slurp the noodles and drink the broth?
That taboo is simply wrong in many contexts. Watch Tampopo after reading this and it can correct for a lot.
It's not a taboo, it's just not considered good manners in formal contexts.
But it's fast and efficient, which is why people do it anyway.
