I joined a really bimbotic forum called Flowerpod when I was on MC, out of boredom and since my metrosexual Singaporean colleague said that "every woman should have a Flowerpod account". (PS: Go join it, it will provide you with tons of entertainment! e.g forum topic: How big is your diamond? Do your SO give you money even if you are working? Are you ok if your SO wears your panties{???}

So I was really scratching my head trying to figure out what the heck does SO mean. Do you know? I mean, if you're going to discuss letting your SO wear your panties you better ham well know who SO is.

So, anyway, SO means Significant Other.

Cheh.( I have to put this in. Really "cheh"-ed me out)

I told you, it's a bimbotic website.
(I have a feeling the panties question was asked by a guy. Oh well, whatever works for them.)
