Parelevant 

Of marginal relevance -- not really relevant, but close enough to maybe be interesting anyway. (From "para" (beside, subsidiary to) + relevant (probative).)

Phil, your job performance this year sucked, although the fact that you always made a fresh pot of decaf when it was almost out is parelevant and gets you some team-play points.

parlavantzas 

Harassment behavior characterized by a one-sided, disproportionate dispute, by a party that was in the wrong in the first place and can't overcome the bitterness of getting punished for their wrongdoings.

The judgement found him guilty more than 15 years ago, yet this jerk keeps his parlavantzas going on his personal blog and in the media.

You have to stop with this parlavantzas, Konstantin! Otherwise things will turn ugly at some point!

prelevant

adj. having direct bearing on matters before they become significant in the public eye; relevant to a matter at a time before it is widely considered relevant

His choice of wearing a Rick Vaughn (Charlie Sheen's character in the movie Major League) costume for Halloween was oddly prelevant at the time.
