I played golf with some ex-coworkers of mine. All the games I had ever played had been fairly quiet and respectful. Towards the beginning of this game, one of the guys hit the ball very badly and I let out a snort/giggle. I thought maybe I was being too rude and asked my teammate Brett if it was okay to laugh. "Oh yeah! It's okay." And we did - the entire game! I think I like any sport where you are allowed to belly laugh.
