"Chopping" is a term used in both contexts ...

When there's split pot you'll hear people say "chop-chop".

When it's folded all the way around to the blinds pre-flop, you might hear your fellow blind dude ask you "Chop it?" or "Chop-Chop?" .. it just means ... "do you want to take our blind back and avoid giving the casino money (the rake), cu'z we're not gonna make much ourselves anyways?".
