At the end of a meal my parents used the phrase, "I am sufficiently surostified! "to mean "I am full." I can't find the term surrostified (using all possible spellings) in a dictionary or on the internet. It was from the Irish side of the family, if that has anything to do with it. Here we have been saying it for all these years and it might be made up. Have you ever heard of it?

Just guessing at it, maybe sur = over, os = mouth + ify from facere = perform as in satisfy?
