That was something that confused me long time when growing up. First I saw it mentioned in passing some American sitcoms, maybe in some movie, then in Usenet discussions etc. Combined with the "American style portions" in some restaurants, I developed a sense of awe when thinking Americans routinely taking shits that clog the toilet. So many, so big shits that their toilets have plungers.
