lightswitch rave 

A rave thrown by rhymatically flickering the lightswitch. Not recommended as lightswitches were designed for turning lights ON and OFF. The Cheat received capital punishment for such crimes.

The Cheat is GROUNDED! We had that lightswitch installed so you can turn the lights on and off, not to throw lightswitch raves!

Lightswitch smoker 

Similar to the lightswitch couple but unlike social smokers, the lightswitch smoker can start and quit smoking at any time, for long periods of time.

Man :I hate lightswitch smokers because I can't quit smoking.

Lightswitch Gremlin 

"Don't turn on the light, don't turn on the light!" Any female who appears attractive at the end of the night, but whose true form is revealed by proper lighting.

Yeah so Gina, right. She was slammin' at the club, right. Then i brings her home and was takin' her to town, right. Then Tommy bursts in the room and turns on the light, right. He's all like, bro-man, that bitch is a lightswitch gremlin!

A couple who is constantly breaking up and getting back together.
