bean ball Share definition Flag A ball that hits the batter. Batter automatically gets to take first base. If bases are loaded, he gets an RBI (although in this case it's more a run beaned in then batted in ;) ) OUCH, again with the bean ball? Come on umpire, eject this maniac! bean ball by anonymous October 24, 2004 0 0 Get merch Get the bean ball mug. Buy Now — $32.95 See more merch
