Short for "International Rugby Board," the world-governing body of rugby union. The IRB is responsible for international matches, rankings, and keeping team managers in check. Similar to FIFA except it's actually effective, not run by complete idiots and hires competent refs.
If it weren't for the IRB rugby would be a clusterfuck. Just like FIFA.

irbulenem 

Your grip on the physical world loosening, your very existence fading, your body disappearing into the void slowly, making room for those the world is worth. Your mind spiralling chaotically down a worsening depression. The very worst of insanity spreading through your mind to the core, until you can't take it. You will either be led into suicide, or Grim himself will personally handle you.
"He was going through irbulenem. Insanity at its very definition."

Brought to public attention by Bob Woodward and Carl Bernstein in the book on the fall of Richard Nixon, All The President’s Men, ratfucker was Nixon’s term for a political operative who sows chaos among opponents; an agent provocateur. It is thought to have originated among campus political rivalries at USC, and seems to have some usage in the US military.
Along with Nixon’s other ratfuckers, Roger Stone caused fights at otherwise peaceful Democratic Party protests to generate a false narrative that the Democrats were violent and dangerous.
