haizi - A Chinese greeting that sounds like 'hello little kid' but i

A Chinese greeting that sounds like 'hello little kid' but it’s so annoying it might as well be a curse.

I said 'Ni hao xiao haizi' to my cousin and now he won’t stop talking to me.

I used 'Ni hao xiao haizi' in a DM and my friend thought I was mad.

I yelled 'Ni hao xiao haizi' at a kid and now he hates me.
