Yes Google controls us.  A quick google of "Washoo" finds that the word has made it into the 'urban dictionary'.

Washoo - An exclamation of surprise while stumbling. A slurred way to say, "Oh shoot!"

It's there but not too popular.  Since 2005 it has had 2 up votes and 1 down vote.

In a quest to set the world right, I have submitted the correct definition of Washoo to the urban dictionary website.  It is currently being reviewed by editors and I look forward to it's publication.  In case it is not published due to some gross mistake here is the entry:

Washoo - Best backyard game in the world.  Example: I'm Jonesin' to play Washoos this weekend.
