Okay, so my friend and I were having a discussion on a few hypotheticals and we'd mostly agree on our answers, but this one got us pretty opposed.

Basically, a young (26, say) human male, who's lived and grown up in the jungle, and is equipped with a rather sharp spear sees a young healthful male gorilla. He decides to go after it, expecting a fight. He stumbles into the center of a clearing, and knows that the gorilla wil attack him (Don't ask me how). So he's in fight or flight mode, heart beating and everything, holding onto his spear for his life, and the gorilla, who we assume to be very angry, jumps out from a random direction.

My friend says he's dead, and starts quoting some statistics or other about how a chimp once pulled 700 lbs or something, and that chimps don't even come close to gorillas, but I think that with how tense he is, he might get a few pretty solid bites but would still stab the thing to death.

Basically, gorilla (male, young, angry, pretty darn strong and from a random direction) vs. human (male, young, expecting of a fight and equipped with a sharp weapon), who wins?

Yes, I realize that this isn't the most plausible of questions.
