OCC
An occ is when you're still the same character, but you're kind of a mess, like you got hit by a truck and forgot your name.
@danny: My character is still the same, but now he's a messy drunk.
@kate: My occ is a disaster, he wears socks with sandals and cries at the grocery store.
@tom: My character is still the same, but he’s now a confused squirrel.
