When you have the option to bang someone and you have nothing better to do and can't think of a good reason not to so you go ahead.
In programming,
If not_to_bang_reason == NONE :
Return bang!
Person#1: I was there and so was he so I tossed him a "why not" bang.
Person#2: *shrug* why not!
Person#1: precisely.
