lightning jack 

A lightning jack is when someone masturbates in record time. Typically used when someone needs to take care of themselves in a pinch knowing they must be quick as they will need to be around others very soon.

Knowing the pool party would start soon, I had to step in the bathroom for a lightning jack.

Jack & Amy Lightfoot 

A couple that showed everyone else what living life truly could mean. That love could keep us alive and once in awhile a cool change IS for the better. That there is a once in a lifetime Lady for one long haired hippy boy up on Cripple Creek.

Damn that couple could be as happy as Jack & Amy Lightfoot one day.
