Similar to north region, south land.

It was originally not meant to mean people" in the first, as u know that peeps from both sides are always on loggerheads, they started off as calling their fellow countrypeeps as bac ky, to show sarcasim, hostility.
Btw, the northern peeps hated those remarks, so they started calling "nam tu" for peeps from the south.

There is always a saying, learn to respect others and u will be respected eventually.

We just use these word to represent girls we wanna bonk
