Okay, so "Olympic" grudge-holding may be a poor name for this particular event of memory. Because I actually never remember this moment except at weird and useless times.
So it's Olympic in the same way it's Olympic if a javelin thrower has no control over when he throws a spear, so he just carries it around with him everywhere so he's ready. Only his arm never decides to throw it at competitions. Instead his arm only throws it at children's birthday parties, Shabbat services and Burlington Coat Factory sales.
