I don't know if Mr. Q took offence, the tone of his reply kind of suggests it, anyway I hope not.
The Dutch actually make a point of keeping the English for it, and have tried to leave a phonetic pronouncation for it that looks like this: "djzio-kesjing"
Now I AM Dutch; and if somebody walked up to me saying that, I would probably roll around on the ground laughing. Must be somebody pulling somebody else's leg - 99% of the Dutch speak English anyway, and certaily in the Geocaching community, so they wouldn't need a phonetic explanation.
In fact my wife (she's not Dutch) tells me why correct them (thats us the Dutch), they provide a laugh a minute with their version of English. She is frequently crippled with laughter when we say "Lets go to the Vimpie for lunch"
