a jewish person who is obsessed with Japan/Japanese Culture/Anime, etc. and attempts to act as if they were Japanese, even though they're far from it. They use Japanese words but usually end up pronouncing them wrong and sounding like total noobs , hanging out in their room drinking ramune and yelling frantically because they cant find something. you will also find most weeajews going to many many anime conventions a year even if they cant afford it.
i was sleeping and that damn weeajew over there just started yelling because he didnt have things going the way they planned and woke me up FML
