A simple minded person that can not handle a stressful situation with any sort of diligence or composure.

Jackporn 

The one porn clip which is of sufficiently high quality and meets ones needs to both commence and finish masturbating in a single stroking session, despite it being the only clip viewed in this particular sitting.

This is an exclusive event and cannot be repeated with the same clip.

I was nearly late for work today,
luckily I hit the Jackporn this morning which saved me a lot of time.
