facemask
A mask made from the face of someone you killed. You probably killed them because they were annoying or they stole your last slice of pizza.
I made a facemask out of my little brother’s face after he stole my phone and my last candy bar.
My grandma made a facemask from my uncle’s face because he kept teasing her.
I used my neighbor’s face as a facemask after he yelled at me for mowing his lawn wrong.
