Ghosty

When smoking a bong; a draw is taken, the mouth piece is then covered, leaving some smoke inside the billy. After holding in the draw, and exhailing, the ghosty can be sucked in to increase the hit of the initial draw.

Some people believe that the ghosty is what gets you stoned, but that cannot be accurately confirmed.

*Takes draw* "Quick! Save the ghosty, it's the best bit!"

"I greened out from a ghosty once!"
