Show name for my gelding?

I know for different types of showing you pick your names differently, I do AQHA and PtHA and APHA where your horse has to be registered and there show name is most commonly the registered name and we come up with barn names lol its kind of the opposite but how we do it is we look at the horses pedigree and use names from it to create a name like my geldings name is HE spotted me he gets his name from his father Will spot ya other examples are will smith or will rock ya other sires like invitation only have foals named invited to the party or Obvious conclusion has foals named better be obvious or its obvious so try going off your horses parents names or grandparents
