More often than not, I see the acronym IANA followed by a profession, with the specialized case of ``IANAL'' for ``IANA Lawyer'', sometimes (often?) with the space dropped. Unfortunately, IANA also stands for ``Internet Assigned Number Authority'', and while I can't think of way to confuse those right now, there's bound to be a way.

(How about ``I don't think it's legal to hijack a reserved IP address, but IANA IANA lawyer.''? )
