a person, place, or thing that represents an abstract image and
can not be fully defined by practical words. (can also be an idea or philosophical stand-point)
I don't know how to describe that (person,place,thing). It is definitely Smek!
it means thats something is is GOOD!
if you win in a arcade geme against you friend, you can say "smek" because you happy, and you did well.
also see "aeg" almost the same thing ;)
