kamioshi

A romanization of the Japanese word for god (神 - "Kami") and push (推し - "Oshi"). This term is used in the VTuber community to refer to your favorite among your oshi, the one you support the most. You can only have one "kamioshi", and a lot of people just don't have one as well.

"Hey dude, did you see Fauna's last ASMR stream?"
"Hell yeah! I love her so much, she really is my Kamioshi, in Hololive at least."
