OOOOO DEEEEEN

“Oooooo Deeeeen” is like an expression that describes how you feel. It can be used instead of “omg”, “wow”, “yay”. But if the feeling in a more sad or serious tone then drop to “Ooooo” and just use “Deeen” it would replace words like “darn”, ”frick”, “barnacles”.

OOOOOOOOO DEEEEEEEEEEN I haven’t seen you in forever.
Deeeeen, someone’s in trouble.
OOOOO DEEEEEN
