Kanye West is grumpy ... super, duper grumpers ... and yesterday Mr. Grumperton took out his grumpiness on a really nice photog -- and it was all caught on tape.
Yesus was walking around NYC with his posse, when a photog -- not one of ours -- politely asked (from a safe distance) ... "What's good, Kanye?"
Kanye's response -- "DON'T ASK ME QUESTIONS, MAN!"
The pap said goodbye to KW ... but then he made a fatal mistake -- he wished Kanye a happy belated birthday!!!
Kanye's response -- SHUT UP! DON'T EVER TALK!
Where's a good parking sign when you need one?
