I was researching something else today and I found the pretty well put together Official Dictionary of Unofficial English (it even has a quote from William Safire on the cover!). And it includes Hrant's famous "bouma", along with a quote from him as one of its seminal uses.
I couldn't find any evidence that this news has been broken to Hrant and the rest of the Typophile community, so I thought I ought to make a topic.
