someone is feeling saos-y

"saos."

it's tagged all over halifax.

i didn't notice the presence of "saos" until a friend told me about a problem he was having...the problem being that wherever he looked while walking the word "saos" haunted him until he reached his destination. after that fateful coffee meet i began to scare myself: "saos" was on my mailbox..."saos" on the bus i was boarding..."saos" all over a grocery store..."saos" on parking meters, on street signs, on coffee-shop doors, on the sides of restaurants. "saos" even toots its own horn downtown on the waterfront.

this friend thought "saos" might be a person who treats his tagging as a job-of-sorts. whether or not "saos"-ing is being treated as a form of employment i still wonder what dire importance might rest within the word. i hope that something moving, inspiring or revolutionary rests between the letters of "saos" and that is part of the reason why the word is everywhere my eyes fall. maybe the word "saos" isn't only scribbled by one person. "saos" could be a sort-of code or secret, abbreviated slogan for an entire collective of passionate people. "sabbatical academics oppress students"? "sick altercations offer sadness"? "sour apples often suck"? WHAT DOES IT MEAN?! is it a name of a person? does "saos" stand in for the four initials of one individual who might have spent YEARS of his or her life painting the city red (and pink, black, yellow and green)? is someone so sickeningly obsessed with pasta sauce that he or she can't control their cravings to yell it at the world (in poorly-spelled spray-paint letters)?

is "saos" splattered all over halifax solely to force neurotic people (not unlike yours truly) to re-consider the scenery, labels, slogans and bits of matter they take in daily?

has anyone else been plagued by "saos" sightings? does anyone out there have a clue what it means?
