Greeting, folk of nairaland!

We discussed your forum at https://kohlchan.net/int/ and got several questions.

1) What does aboki mean?
2) Which ountry do nigerians like more - Ukraine or Russia?
3) What does Olosho mean?
4) As far you know, polish people are black people of europe. Whould you accept Polish neigboor? And in case he won't steal your stuff?
5) Why do you say, that traffic lights don't actually work in Nigeria?
6) Who are yorubas, oinbos and igbos?

Best Regards,
Bernd Lauert.
