Jacking Off

When a man who looks like their name is Jack. Just goes off on someone when they are really mad. And puts their hand into a fist and starts shaking it with rage.

Bro I think Jack is about to start Jacking Off.

fractal jacking

The practice of videotaping yourself masturbating and then masturbating to the video. The process can be continued ad infinitum, till you have created a fractal of narcissistic pornography.

Fractal jacking is one of the top ten pastimes at Harvard.

I just reached the hundredth iteration of my fractal jacking; time to celebrate!

Spoon Jacking

A true test of male bonding, whereby one gentleman of sound mind and kindred spirit, befriends a casual aquaintance of his dearest fellow stag, and understands the pressures and limitations of a "spooning" relationship, and feels the desire to aid the demands of the female entity, and hence "hijacks" a proportion of the workload, of course with the best intentions for all.
After which, an agreement is made to perpetuate this arrangement until the needs of the damsel have been adequately fulfilled

Michael: That birds been around a few times this week mate, are you sure you're up to the task?
Peter: Not a problem, my friend JC has been more than happy to share the workload. And even though I cannever recall asking him, I'm relieved he's there for me
Tim: Seems like a clear cut case of Spoon Jacking to me, and we should all be very grateful

flap jackin'

A term for a lesbian sex act similar to scissor sex where the action moves from side to side rather than back and forth. the term derives from the stacking of labia which resembles a stack of pancakes.

This scissor sex isn't hitting it, it's time for some flap jackin'.
