Kay-bin.
It reminds me of the property manager at my first apartment, back in 1990. She spelled her name “K’ren”, and I assumed it was pronounced either Karen, or kuh-Ren. Nope. It was “KAAAAYYY-WRREE-NNN”, three syllables in her very southern accent. The stress was on both of the first two syllables. 😂️
I don’t get tiktok either, but I have a friend who seems to spend hours on it every day.
