Pushing peeps in the creek.

I don't know if anyone is still giving their opinions on phrases, but here's one I have been unable to find anything about.
My grandmother, who died in 1973, used this one when someone would ask her to do something that she felt was asking a little too much.
"You wouldn't push peeps in the creek, would you?"
Any thoughts, by anyone?

The phrase people are still here. The site owner started a new discussion page today. Past opinions are archived.

Grandmother may have been using "peeps" as slang for "people."
