kpop had altered my interpretation soo
I used to think it meant a long, exaggerated, held out "so". Kinda the equivalent of "so..."
but nope. now it's short for my husb-- oppa's name: kyungSOO.
And pretty much any Kpop/krama star
such as kwangSOO - who I adore in Running Man
or like Infinite's MyungSOO
