It's on the Tip of My Tongue

You know that feeling you get when you've stayed just a little too long at a birthday party? It's not simply tiredness or boredom or buttercream-frosting-sickness. What is it?

Our friends in Estonia have the answer:

Sünnipäevanädalalõpupeopärastlõunaväsimus

In other words (as George W. is fond of saying), "birth.day.week.end.party.after.lunch.tiredness."

Remember: although Estonia was part of the former U.S.S.R., the Estonian language is unrelated to Russian or any other Slavic tongue. Estonian's closest linguistic relative is Finnish.

Update: The originator of the "word," Corcaighist, explains that it was all a linguistic joke.
