In reply to Chris_Mellor:
Some people make noises when they climb, doesn't bother me.
I occasionally make get a bit shouty for the odd move if I'm on steep compression stuff, must help keep tension or something, less often of vertical ground. Also known to throw a bit of a paddy if I drop the last move on something I've been working for a while.
My girlfriend used to make noises like she was being tortured and another friend's girlfriend used to make orgasm noises. All entertaining.
