mistake whale 

A person that makes a big mistake or a bunch of recurring little mistakes that add up to a big huge whale of a mistake.

My biology partner is a mistake whale, he always fucks up when we have a lab.

One who either makes a big mistake or plenty of little mistakes which combined make a BIG MISTAKE!

My biology partner is a mistake whale. He fucks up nearly every lab we do.
