If by weeb, we mean those disgusting slovenly fat anime consumers, I doubt it.
The proper way to eat sushi is washed hands. Many Western mannerisms while using chopsticks, such as jamming them onto food sticking up, slamming them head down to align, and rubbing them together are considered extremely disrespectful and rude.
It's simple, it resembles this:
(Praying to the deceased at a temple/folk religion stuff, note the "sticks" in their hands and more sticking out in that cauldron-like vessel know as a Ding)
Mannerisms are oblivious to weebs of course, they are the lowest of all lows, all their supposedly Asian culture is obtained from anime, or the "good portrayal" of it. Mianzi and tiger parenting? Nah.
I would love to see gaydur eat his shitty Taco Bell pizza and burritos with a pair of chopsticks.
(Speaking of weeb, thanks Nool, you fool. At least we get to see what the feeder's wankbank looks like for a day)
