obnoxioucity
how much someone wants to be the center of attention, even when they're not good at it
My cousin's obnoxioucity is through the roof. He interrupts everyone's conversation to talk about his day.
My friend's obnoxioucity is like a show. He talks over me and everyone else.
My brother's obnoxioucity is legendary. He yells at the dog if it doesn't listen to him.
