Wow, been so long since anyone's placed a new term.. (even though we have TONS of them now)
I got dibs on putting the term "AURA" in here.
1. Aura = Those 30 minutes of boosted exp you get when you log in for the first time after 12:00 am ogp time.
2. Vent = Ventrilo (Usually meant as the guild ventrilo) If you don't know what vent is, it's a program where a certain amount of people can log in from thier computers and speak to other people with the assistance of a microphone.
3. Guild -> Vent = A notification to get on the Guild Vent.
I'll think of more, but everyone is welcome to place more in here.
