The right term would be »sign language«. See the list from Luc Devroye.

ASL. And the proper term is mute.

Unless they are REALLY good at pinball, in which case deaf dumb and blind is appropriate.

It is offensive to my deaf and non-speaking friends and my mother-in-law who taught my son ASL, and all of us, and signed for the deaf for 50+ years would kick some butt! I would hate to go up against her and she is 81.

Got the joke Darrell :-)
