Если вы скажете американцам про "зверствующих бобров", вас могут неверно понять.
"A wide-open beaver was a photograph of a woman not wearing underpants, and with her legs far apart, so that the mouth of her vagina could be seen. The expression was first used by news photographers, who often got to see up women’s skirts at accidents and sporting events and from underneath fire escapes and so on. They needed a code word to yell to other newsmen and friendly policemen and firemen and so on, to let them know what could be seen, in case they wanted to see it. The word was this: “Beaver!” "- Kurt Vonnegut, "Breakfast of Champions".
