Bait N' Switch

N. Deceitful social technique used by nubile young twenty-somethings to introduce potential suitors to their friends.

This technique involves an attractive woman hitting on a man. She is the lure, dangling in front of the prey. When the man is significantly invested in the conversation, the woman introduces her friend with the glandular problems and lazy-eye(s). The attractive woman (the bait) disappears and the switch is complete.

Poor Steve found himself a rocket, but she pulled the ol' bait n' switch on him and now he's stuck over there with that tugboat friend of hers.

Light-Switch Bitch 

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.

(In the weight room)

Girl coach: How was your night?!
Athlete: Great thanks for asking!
Girl coach: WHY AREN'T YOU DOING ANYTHING?! GET TO WORK DAMMIT! YOU'RE SQUATS ARE TERRIBLE!
Athlete (to fellow athlete): Coach is such a light-switch bitch.

Bate and Switch 

When masturbating in a common room when other people are at home, you have a backup tv channel ready to quickly switch to in the event that someone walks in.
