Combination of the word 'distracting' and 'procrastinator' - Someone who's pulling you down from whatever task is at hand by distracting you with their non-work-related antics.
Coworker: (doing work) Cut it out Janice, you're such a distractinator!
Janice: (throws paper airplane at coworker) Heads up, man- again! Hahaha!
When you're getting called out on your bullshit and you need to quickly derail the conversation, accuse your accusers of distracting from the real issue.
"Hey could you stop talking over women?"
"I can't believe you're distracting from the real issue, class. You make me sick."
