There's an acronym I just made up that I think the online community could use: IPRL. Short for "I plead real life." The idea is that if you haven't done a created a wiki article like you meant to, or if you haven't updated your blog for a while (not that that's ever happened here) you can plead real life. Say "I have a job/family/rooftop pigeon coop/what have you. Sorry."
The letter combination has been used, but not for this. Although "isolated perfused rat liver" does sound like it could make a good appetizer.
Anyway, I figure if there's one thing the Internet needs, it's another acronym. lol
