Karo Bukan Batak (Karonese is NOT Bataknese)
1. KBB. End of discussions, since only "Batak Toba" which qualified as "Bataknese", not Simalungun, not Karo, not Pakpak Dairi, not Pasisi/Pesisir/Central Tapanuli, not even Mandailing and Angkola

Never trust everyone who says otherwise, at least never trust people who mislabel "Karo" as "Batak Karo"
2. X: Are you Bataknese?
Y: KBB, dude
X: KBB? WTF is that?
Y: Karo Bukan Batak (Karonese is NOT Bataknese), so think twice if you assume Karonese as Bataknese, because it's so racist and rude against Karonese
