oh.

when you are let down or dissapointed over text. also used for extreme sarcasm. the lowercase letters indicate casualness but the period completes the emotion. i cannot properly explain it's meaning in words, it is rather the feeling from seeing it.

you and your friend are talking about how you did bad on a test:

lauren: you sounded very unprofessional...
lauren: the writing was not right.
you: i know i am stupid i made a mistake
lauren: i don't care.
you: oh.
