That girl who you just cant find anything to bitch about. Always really nice, but never too nice. Generally quite smart and can be blushingly nerdy, but the type of nerd that everyone loves. Has an awesomely wicked sense of humour that's so witty and can burn people to the ground. Someone everyone wants to be friends with.
Also the famous kiss song
and the name of the sickly beth in little women.
Often the shortened name of Elizabeth or Bethany but Beth's loathe being called anything but Beth (especially Elizabeth nicknames like Lizzie and Betty)
Wow isn't Beth so nice?
Man, Beth's smart and funny. She just cut me so bad.
