1. In Baseball or Softball, to achieve a
home run by hitting the ball so hard that not even the player who stayed home with his sick kids could
catch it.
2. A single hit that is so vicious that its effects are felt for a while afterwards, usually through flying backwards, falling to the ground,
writhing in pain, and throwing up. Bonus points if you do it with a baseball bat.
Aaron tried to
sneak up on me while I was blindfolded, but I kicked him in the
groin, which caused him to be knocked out of the park.
