What is clamming in horse racing?

Answer 1

Well, there's a races called "Claiming Races" You enter your horse in the race. And if people want that racehorse they drop a note that says, "I claim 'this horse' And they'll shake it and whoever's name is pulled out, it's the person who claims it.

They give a price for each horse for like $25,000 and the people at the track claim the horse before the race is run. You don't have to claim a horse though.
