An exceptionally long episode of masturbation fits. These episodes are usually brought on by sexual deprivation and bordom; however, and I'm not making this up, they have been used a means of fundraising for sexual related causes such as safe sex. A masturbation marathon is a strenuous event that requires disciplined training and preparation. There are several related subcatagories such as time, ejaculation distance, and most orgasms for both male and female competitors (I'm totally serious - google it).

Something of a daily occurance, NCIS is a great show and it seams its so great that they have "Marathon's" almost everyday. Do not get sucked in as these last for 12-24 hours and you will get nothing done.
Person 1: I'm going to work on my project *walks into TV room* EWWW!!! NCIS Marathon! *Two hours later*: Shit I got nothing done!

In short don't get sucked in.
