It's is the name of the hot blonde female protagonist in a 90's TV show called 'Buffy the vampire slayer' played by
Sarah Michelle Gellar, In which
Buffy Summers denies all the laws of female blonde girls in
teen movies by actually punching people in the face instead of screaming and running for help. Many geeks and even non geeks have begun worshipping the series as it turns out to be really good even though it looks like some Twilight prequel.
