When one girl walks in to find TWO girls (not sluts, of course *cough cough*) waiting for one boy to return with body shot materials (aka Lemons) a countdown commences giving said girls and said boy enough time to save their lives before punching bitches in the breasts begins
5...4...3...you do NOT wanna meet me, I'm a HUGE bitch!...2...1 *girls run screaming out of the room scared as SHIT*
Dude, did you see that Bitch Switch Countdown in room 6532 last night?!

A woman who goes from being awesome and friendly to a complete bitch faster than you can blink. In these women, it will seem almost as if a light switch is flipped inside of them and BAM! they will morph into bitchy bitches.
