Charm Dust 

The little pile of saw-dust like cereal at the bottom of the Lucky Charms bag, that no one likes to eat.

Brother: Here you go bro (hands him box of Lucky Charms), i made sure to leave you some.
Other Brother: aww c'mon man, you left me the charm dust!
Brother: sucka!

Charm Dust 

When a girl farts.

She couldn't help but laugh when she saw the look on his face when he realized his girlfriend had just charm dusted him.
