Kanye West has had enough of getting robbed ... which is why he's ranting about other rappers -- like, possibly Drake -- jacking his floating stage.
Kanye went off during his show in Edmonton this weekend, and screamed out, "This the original! Accept no imitations!" As he marched around his floating stage ... he went on to accuse performers of stealing all sorts of ideas from him.
He never mentioned anyone by name, but it's worth noting Drake floats through parts of his shows, but he's been doing that for a while now. Maybe 'Ye just found out?
