An acronym for Snotty Bitch Face. SBF is a play on SPF, sun protection factor, indicating the magnitude of a woman's hotness and bitchiness. SBF ranges in values similar to sun block ~ 0 - 50, 50 being the hottest, bitchiest woman possible.
Man, check out that bleach blonde with the pointy nose in the Mercedes; she's an SBF 45! ... SBF (snotty bitch face) ...
