As the other definitions have said.

Can also be someone or something that spoils the mood for just about anything.
We were watching a great movie, with an enjoyable plot, good acting and top notch special effects. Then Bob starts nitpicking something that once we thought about it, it totally ruined the movie for us. That guy is such buzzkill.

So, I'm talking with a few diffrent people on MSN Messenger, alternating between them. We've all got interesting, intelligent conversations going. Anyway, suddenly one of them chews me out because he feels I'm not giving him enough attention. He totally killed my mood. What a buzzkill.
