look up any word, like the eiffel tower:
Adjective and synonym of the word "so" derived from taking all the excess "oooooooooo"s from a long, drawn out version of the extended"soooooooooooooooooo" and replacing it with a single "x" to save space while talking and texting to others.
"That boy is soox dreamy!"
"I know, he totally is!"

"That duckling is soox teensy!"
