Orre is the definition of someone you invite to a party just so you can fuck her/him.
Orre can also be used instead of the term slut/whore.
Actually, Orre can be used in any situation.
No one really knows where the word "orre" originated and what it's original purpose was. All we know is that it's totally awesome.
