"Where is the popcorn tinsel?"
"In the bag, inside the kernals."
"Someone's being Crampissed"

Cramish is a word for very VERY VERY close friends, even if they are miles apart. They are meant to be insperable and even if they have MANY fights, they will always be best friends. Usually, people who are in CRAMISH, have different personalities from each other which makes them unique in their own way. This also keeps them close together, Forever.
