It ' s down to the way condoms used to be tested , which was blowing them up with a set amount of pressurised air . Too small a condom and it ' d fail for no reason , too large and it ' d pass without meeting the standard , so they set a size range . It ' s woefully outdated . Recently the argument for not allowing larger is that insecure young men will buy the biggest condom they can leading to an increase in the failure rate . I think that ' s nonsense , as nothing is quite going to say ' look how small my dick is ' more than a baggy condom that slips off . <| sep |> Dinar or denarius maybe is where the word dinero came from ? Sorry , tried to link to the history section of the wikipedia page . I don ' t know they just sound similar . I was kind of drawing a parallel between ppl still calling money paseta . Sort of like , what if the word dinero is a relic of using a word for a currency interchangeably with the word money .
