I'm working on a Windows Phone App without purposes profitable, just for study, and I need a voice male saying "I don't care" in two different shades:
Loose - Like when someone comes to you and start a random conversation and you just want to relax;
Trolling - Like when some friend is talking and you don't give a shit, and you cut his speech.
Trolling - http://youtu.be/4iH2-xbYVYA
I hope those descriptions are sufficient.
Do you still need this?
