Ssni945+while+my+boss+was+awaymei+washiohd

Breaking it down: "ssni945" could be a code or ID number. Then "while my boss was away" is a normal phrase, possibly a play on words. "Mei washiohd" is confusing. Maybe "mei" is a typo for "my"? Or a name? "Washiohd" might be a mispelled version of "Washington". Maybe the user is making a joke or looking for a specific term.
