Jerkless January 

Jerkless January is an event in which, if you failed NNN, you are to go the entire month of January without jerking off, for if you failed NNN, you will be redeemed if you participate in JJ, but if you fail NNN AND JJ, then you will be classified as the inbred fucking failure you are (but only if you decided to participate in NNN (or JJ) in the first place)! People who won NNN can also partake in JJ, anyone is able to do JJ, and besides, I`m sure it would be good for you if you were the retard who decided to participate in Destroy your Dick December.

Fred: Zack, I think I`m gonna participate in Jerkless January this year.
Zack: I believe in you! We may have failed NNN, but we will not fail this month!!

jerknesia

The after-effects of a long wanking session that results in the forementioned wanker falling into a wank-induced coma...leading to total loss of memory of the wanking.

Her: So you just jerked it all night?

Him: I don't know, I must have jerknesia.
