What kind of name is Joi? Seriously

I was at some dinner thing and started reading the message board from my Visual Communications class last semester. I was with Jess and Jo, and Tim and Katie from my class were there, though I didn’t speak to them, and I was waiting for my grandmother and aunt. Jess and Jo went out to pick up food for us since we were starved and tired of waiting. While they were gone, I searched for my name on the message board and got weirded out when people were asking if I was dating someone- until I realized I typed my name as ‘joi’, and they were asking about a joil dating someone. Then Jess came back with vegetable fried rice and I hugged her before waking up.
