"worshipful" is the response you get when your obedience is very high compared to the required obedience for that action. the worshipful responses were added in 0.2.2
I think the response that requires the most obedience is the 'worshipful' reaction to you cumming on her face while she's asleep. I think that requires around 75 obedience (but I don't expect anyone to attempt it, just use the console command 'set_attribute_level obedience 100' if you want to see all the responses)
