Usually a precursor to the word "hot" when linguistically challenged SweetVally High girls describe the attractiveness of girly-men like Ashton Kutcher
"OMG OMG OMG Aston Kutcher is like, sooooo hot!"
"Like, I know. I hate to change the subject when we are talking about Ashton, but do you have any Vagisil?"
Identical to the English word "so", except with extra O's added for extra emphasis. Often used when waiting for a response, or when intensifying an adjective.
Soooo...did you get my last IM or what?
This movie is soooo boring!
