From what I've seen online, and in the dojo, most people who are rolling in bjj are relatively silent. There is a lot of panting, a bit of grunting, some heavy breathing, loads of sweating. You know, the typical sounds for someone who is working real hard, using their muscles, etc. Pretty typical. But I am amazed and amused by the sounds the hubby and I make while rolling.
Here are some examples of things you may hear us utter - some are pretty standard terms, others, well, not so much. It's our own bjj lingo:
tap : verb
1. My hands are trapped in some terribly unfortunate position and I can't get them free to tap
2. You won - now back off
chest : noun
1. You are crushing my chest and I can't breath. Let up a little.
oooof : onomatopoeia
1. You have just crushed me and I don't have enough breath left to say 'chest'.
whOOoo oooooo : onomatopoeia
1. You have just twisted me into a pretzel and I have no hope of escape. This is often followed by 'tap'.
shit : expletive
1. You have gotten me into a choke. Again.
2. I am trapped and utterly helpless. Again.
no no no no no not that not that : revelation
1. I am about to be twisted into a pretzel or some other unfortunate position like back control and will twist my own self into a pretzel to try to avoid it.
uberhootentrout : nonesense
1. the universal release word, similar to 'tap' in that it means 'let me go now!', but different in that no one can remember that word when it's needed most.
You should try bjj. It's fun. Really.
