look up any word, like trill:
 
1.
A code word used to describe going out drinking and partying. Said in jest, because of how goody-goody's view said persons drinking alcohol - as if it is so terrible they must be "punching babies".
"Punching babies is so fun! Can you hand me another beer?"

"Man, I really want to punch some babies tonight! Where's the party at?"

2.
The act of repeatedly fisting a pregnant lady.
Banging her mid pregnancy felt a little discomforting, so i opted to just go punching babies instead...
