The girl a guy keeps leading on even if not entirely interested in her, as an ego boost or backup just in case the girl he really wants turns him down. Usually the girl he leads on has a crush on him, and is okay with being lead on, because she's still getting his attention.
She really liked him, but she was only his backup bitch.

Two or more bitches in a group with a leader (usually a hotter chick).
If the hot chick wants to get in the face of a rival, she brings along her backup bitches cause she is too chicken shit to go solo.
