Maccometer
A maccometer is how much someone loves to stick their nose in your life like it's their job. It's like they're the most annoying person on the planet.
My neighbor's maccometer is through the roof. She knows everything about my life like it's her business.
My friend's maccometer is so high, it could make a mountain.
My cousin's maccometer is wild. She knows everything about me before I even tell her.
