“I’ve never seen a juice box, but I hear they pack a punch”

The expression “pack a punch” means that something has a powerful effect or impact. It usually doesn’t mean to “pack a fruit punch drink,” but there are jokes. “This morning i watched my mom put a juice box in my lunch bag. she sure can pack a punch” was posted on Twitter by nicole on September 29, 2013.
