A C-16
A C-16 is someone who loves to stomp on your thoughts like they're a kid who just stepped on a ant and didn't even say sorry.
My boss gave me a C-16 for saying the company was a mess in front of the whole team.
My cousin got a C-16 from my aunt for telling her she looked like a raccoon in the morning.
My friend got a C-16 from his teacher for saying the math test was impossible.
