A neologism based on the abbreviation p.r.a.t.t. for "previously refuted a thousand times", referring to any claim that has been previously debunked, shown to be false, publicly challenged and defeated, or otherwise shown many, many times to be demonstrably and verifiably wrong... and yet continues as a claim by believers in pratt.
The dustbin of history is filled with pratt.
