Haibo
A loud, rude, and totally unnecessary ‘no’ that South Africans yell when they’re too lazy to explain why they’re mad.
My cousin said ‘haibo’ when I told him I was going to the party without him.
When my brother tried to steal my phone, I said ‘haibo’ so loud the neighbors heard me.
My teacher said ‘haibo’ when I told her I wasn’t going to do my homework.
