A fictional universe in which "Buffy the Vampire slayer" and "Angel: The Series" take place. Often used by 'net fans on messageboards. See Jossverse.
Fan 1: Last night's ep went against views established in the Buffyverse!
Fan 2: STFU! Sp!ke is soooooo hottt!!11
The fictional tv universe in which the show "Buffy the Vampire Slayer" and it's spinoff "Angel" take place. It differs from the real world in that if there were really vampires and demons running around people would fucking notice and it'd be on CNN and Jerry Springer.
Scotty: I wish I lived in the Buffyverse.
Joel: Why? So you could get fucking capped by a demon or some shit?
Scotty: No, so I could bang Faith.
Joel: She'd kick your loser ass.
Jerry Springer: Now Spike your girlfriend has a surprise for you.....that's right she's having a black man's baby!!!
Spike: **snaps Jerry's neck**
Term used by fans of both "Buffy the Vampire Slayer" and "Angel the Series" when too lazy to write out "BtVS" or "A:tS" or "BtVS/A:tS." Not to be confused with the alternate universe in which Firefly take place (though that is included in the Jossverse).
Fan 1: OMG, like, I so wish I lived in the Buffyverse.
Fan 2: You mean BtVS or A:tS?
Fan 1: The Buffyverse. Doesn't matter which show.
