Well, not only in the States, I'm afraid. Although the States does indeed have a reputation about this. Of course, reputations are not necessarily based on facts or truth. I can tell you that the word "bigger" or words of similar meaning, are used very much when Americans are being parodied in Europe.... Even when the parody is not written in English, the English words "bigger", "taller", "higher", "longer" etc. are still written in English.
