When someone is by themself, and to pass time, jerks off as many times as possible in one day.

Dharshan:Chris you look so tired today. What happened?
Chris:Well, I was up all last night.
Dharshan:Chris! You gotta knock it off with all these midnight jerkathons!

jerkawhore 

A jerkawhore is someone who either steals your comfy rolly chair, eats food in front of you without sharing, or doesn't appreciate their heartfelt secret santa gifts. It can also be used when one feels like saying something ridiculous that rhymes with dinosaur.

Get out of my car, jerkawhore!

jackathon 

A long period of male masturbation generally watching porno films. Sometimes the man will squirt his load on a models picture.

Today I think I will have a Jackathon as I have a big load to shot on her face.
