I do have a question----when someone signs that they are "fully deaf", sometimes they will use a non-dominant "S" with a dominant "five", thumb stuck into n-d hand and the "five" flips up. (Not sure I'm explaining this right.) I've also seen people use it for "ignorant." So, I'm wondering what exactly is the gloss or interpretation of this particular sign? I don't want to risk offending anyone by using it incorrectly.
