ear-lobe skin
the saggy part of your ear that people can't help but grab, even when you're not doing anything wrong.
My teacher grabbed my ear-lobe skin for no reason. I had to sit in the back for the rest of the day.
My brother grabs my ear-lobe skin every time I win a video game.
My dad grabs my ear-lobe skin every time I say I'm not going to clean my room.
