Here are some that I don't think have been mentioned before. There are some that may be innapropriate socials, ultimately, just because they may have more specific role-related purposes (like pray).
Pray <name> would let you kneel and pray to the deity of your choice.
Shake, or something like this, as a compliment to nod. So we can shake our heads 'no' to indicate dissent.
Whine, for obvious reasons. Alternately, we could have Moan.
Throw <item> lets you throw something at the ground or across the room.
Grunt, to indicate your recognition of someone else without having to utter any words.
