My family always uses it when talking about the dog going caca. It used to confuse me when I was a kid but we’d say shishi for pee. Family is mixed so it’s not really pidgeon but more just mixed. A Korean friend heard me say shishi once and said they say the same in Korean, which was surprising to learn but like caca it’s probably a fairly universal word Don’t have any Korean or French heritage myself
