But, eh, who the heck (who the heaven?) is Angelus?
Angelus was the name that
Angel used when he was an evil vampire, before his soul was restored and he became a good vampire.
Jensguy's snippet was a parody of the eventful moment in
Buffy The Vampire Slayer when Angel slept with Buffy and - because of a gypsy curse - promptly reverted to being Angelus and pure evil.
