Starjacking 

Using the free Starbucks coffee house wireless internet access without going inside the store to order coffee.

I drove my car to Starbucks, pulled into a parking spot up front, kept the motor running, whipped out my laptop and did some starjacking. I emailed all my friends for free!

slapjacking 

To jack off slowly not with the purpose of ejaculating but with the purpose of getting primed up for your significant other to walk in and finish.

Shook was slapjacking in bed waiting for his girl to come in. She never walked in and the slapjack went to a fulljack.
