Disorder affecting thousands in the US and portions of Canada. Symptoms include racing thoughts of white pants, uncontrollable urges to manhandle fluffy red hair, blindly disregarding proper spelling rules, and feigning an interest in map-making.
ICL is thought to be caused by overexposure to the portraits and writings of early American explorer William Clark. As of 2011, there is no proven cure. Sufferers of the disorder are said to have reegretted no-thing &c.
Park Ranger: Miss, you can't stand that close to that portrait of William Clark!
Young Lady: CLAAAAAAK.
Young Lady's companion: She can't hear you Park Ranger, she's suffering from Irrational Clark Lust.

The state of existence where every thought is dominated by the sexiness of French Revolutionary Camille Desmoulins. All other habits cease, and the victim drools over google images, books, and films pertaining to Camille Desmoulins.

like a rationale, but insane rationally!
something people base conversations, politics, ways of being or actions on that makes no sense, or is based on a logical fallacy.

eg: James has got a parking ticket, therefore he doesn't respect society and should be stopped!
person 1: James has got a parking ticket, therefore he doesn't respect society and should be stopped!
person 2 (in their own head): that's an irrationale.

Irration is the opposite of ration (which can be defined as a fixed allowance of some kind, ea. food).

Irration is the infinite contribution of whatever you would like. "Ask and you shall receive".
Welcome to your new world! Here you can allow yourself to be the irrational being you truly be. And here's your irration card. It has unlimited amounts of whatsoever you care for and has infinite validity. Have fun!
