Donked Up
Mistake, another way to say messed up. Generally a simple mistake that can or will lead to a greater error. Associated with problems that can take a while to figure out. Including homework, research, art, anything with a challenging and everything in-between.
I really donked up my homework, I thought Hydrogen had two electrons when it really had one. I wish my teacher had pointed out my simple mistake earlier instead of handing me back my paper marked up with highlighted errors. D:
