Offering 10 coins as a reward.

In Tanzania, I saw someone say "Iiiiii anayohaa anayohaa" to an East Asian person, and I'm not sure what it means in a group context... It doesn't seem like a good thing given the atmosphere... Even ChatGPT's answer wasn't helpful... They say it's a greeting, but watching the video, the atmosphere suggests it's definitely not a greeting. It feels like mockery...

Offering 10 coins as a reward to anyone who can tell me.

I wanted to post this in the Q&A section, but there's no option to upload videos there...
