Is what you do when your parents arent home. If they are, that may be dangerous. It means masturbation in case you didn't know. Its also a funny way to say it.
(no parents in your house):
You: *fap fap fap*

(with parents in your house):
You: *fap fap fap*
Your mother: (opens door) Son i need that...
You: *fap* HOLY SHHI- (falls down the bed, grabs everything and does a tornado flip)
Your mother: (closes the door)
