You know how gorillas are really big right? So imagine
Harambe was back on
earth (bless his
soul), and he blessed you with his enormous girth. Now everything you do, you're accompanied by this gigantic gorilla.
On the other hand, I'm done is used when you're tired of someone's shit. Now imagine you're done, but accompanied by a gorilla.
This is the next level of I'm done. I'm gorilla-done.
