look up any word, like sex:
 
1.
A swift, decisive punch to the abdomen. Should the individual be pregnant, it would most likely cause a spontaneous abortion.

An abortion punched must be 'called out' so that is fair game. Much like the ball tag and cooter cudgel.
Nolan: I abortion punched that pregnant girl so hard her baby shot out at 65 miles per hour and killed that Vietnam war widow!
