So that's what it's called..

I did this often just to spite my siblings

Did you mean me? Because this is me

My brothers and sisters made me like this. They would always take my food cuz I'm the youngest.

My cat used to do that when we got our new one, and she got really fat. We had to put her on a diet and feed them separately until she decided she had sufficiently asserted her dominance

Did the idea for this post come from that recent Markiplier challenge?
