Japanese people sometimes say “Gaijin” (外人) instead of “Gaikokujin” (外国人). Weebs will say both mean foreigner. But it's wrong.
I always tried to prove that Gaijin is racist and the weebs say "You're a loser, fuck off! bla bla it just means foreigner!"
I was sniffing the truth every day. Trying to prove I'm right until...
I found that Japanese also use “Gaiji” (ガイジ) offensive slang meaning “retarded.” when talking about foreigners.
the difference is just "N" some japanese don't even pronounce the N and call you "retarded".
I’m a Japanese scholar without ever studying Japanese. I'm better than people with N1
