My Latin does not match Faldage's but I believe it means "Let it be so." And Wordwind, I am deeply regretful that you do not share my feelings about "flense" meaning quite a different action from "rasp". To me the difference is one of the reasons we study words.
Just to tease you, I suggest you inform yourself, if you do not already know it, about the rasping texture of the cat's tongue, and the peculiar similarity with the tomcat's treasure, which in operation elicits a ludicrous alternately gratified and outraged vocalization from the recipient.
