It's not gibberish and it doesn't require any particular understanding of the deranged workings of the poster's intellect to understand it. What it does require though, to unravel it all, is a certain sense of mental flexibility and educative reasoning capability. You see, it's rather more an example of black humour, the term as used in the theatrical sense and not in any racial context of course, combined with references to English, German and Uruguayan history, Mexican geography and Spanish with an example or two of basic psychological dogmatism thrown in to muddy the waters for all but the most informed and deductively competent.
Here's a clue or two to aid as a navigational beacon . Edward II was a king of England who is widely believed to have been murdered at Berkeley Castle in 1327 on the orders of his wife's lover Roger Mortimer. The manner of his death was not pleasant by all accounts. Fifteen men held him down under heavy cushions while a hunting horn was inserted deep into his anus. Into that horn was thrust a long piece of red hot metal which was twisted and turned around his bowels until he died in screaming agony. No mark was ever found on his body to suggest foul play. Hence of course the reference to Cuernavaca and horns. But then you'd need a basic knowledge of Spanish to translate the name of that charming, but now drug ridden, town in Mexico.
Who was Eric Langsdorf you might ask? He was the captain of the German pocket battleship Graf Spee, involved in a little sea action, 1939, with HMS Exeter, Ajax and Achilles(New Zealand) with HMS Cumberland coming up from Las Malvinas. Some of us are interested in raising the spirits of the dead from time to time in the interests of cultural and historical verisimilitude and in keeping imaginations somewhat on the spectromatic dark side.
That last sentence might be construed as approaching the boundaries of gibberish if one didn't think about it very contextually carefully.
