LBH

so yesterday Liz is getting ready for class and rambling as she ususally does. I cant remember what it was that she was talking about but i do know that at the end of her statement she goes:
" i mean LBH... you know what that means right?"
NO. no i did not know what that meant... so i made my best guess
" Uhh... LOVE BIG HAIR?!"
what do i get in response: histerical laughter
What do you think LBH means?
