If someone goes to bed before you, wait until the lights are off. Creep into the room, stand as near to their head as possible and fart. The Ghost part is doing it in the dark, the Whisper part is the fart.

If they find out, let them know, "You have just been Ghost Whispered!"

This Jazz Cabbage got me zooted. Jazz Cabbage is less harmful than Squares. I’m smoking that Jazz Cabbage boy.

I just Ghost Whispered you!
