The act of penetrating a pen light fully into someone's ass while the light is on and facing out. Then turning out the lights in the room creating total darkness except for the back porch light.

GREEN PORCH LIGHT 

When driving by a house with a green porch light on, Make sure to honk your horn in support of Marijuana use. Or knock on the door for a trick or treat.

Hey, look at that house with a green porch light, lets honk to support pot heads everywhere. If you knock you might get lucky, as someone could be waiting with a sack or a joint to share with you.
