Carpe Jugulum is a comic fantasy novel by Terry Pratchett, the twenty third in the Discworld series. It was first published in 1998.
In Carpe Jugulum, Terry Pratchett imitates the traditions of gothic vampire literature, playing with the mythic archetypes and featuring a tongue-in-cheek reversal of 'vampyre' subculture with young vampires who wear bright clothes, drink wine, and stay up until noon. The title is a play on the Latin phrase carpe diem ('seize [literally, "pluck"] the day') and 'Jugular vein' - in other words 'Go for the throat'.
