ss stands for "similar structure"

There is an undeniable pattern occurring with girls from schools with high asian populations. Many girls, particularly asian ones, seem to have the notable "small and thin body frame" hence my friend & i have decided to call this group of similar, ununique girls "similar structure", ss for short. SS's are tend to be asian, and usually gather in groups. SS's are very hard to tell apart so to separate them you must find keen, precise semi-unique characteristics about them.

ie "chink" - chinky eyes.
ie "leader" probably the most valiant and stands out even though shes short, she is outspoken and sporty and catholic
ie "baby face" 16 years old but still looks like she is in the 5th grade, especially because she just got braces and when she wears her glasses

Along with their small body frame ss's have, but are not limited to, smarts, ap classes , school spirit, sports, soft voices.
My school is full of ss's =(

Dude ss average! right there!

So far as of May 27, we have named 15 ss's
