Okay! You gotta translate that! :-)
Russian pilots have no culture. That is they are uncultured or uncivilized, which translates, I think, to something of an insult in Russian. (Of course that's true of many of our younger pilots as well. :) )
If my wife's step niece had been about, or one of the wife's sisters in law, I could have gotten a real translation, the three of them being native speakers of Russian, instead of using Bablefish. But I ran that translation from English to Russian and then back, and the general meaning was preserved. When tried "unclutured", the reverse translation implied something not grown in a nutrient broth in a petri disk. :)
