I would say that a "Shove" can be described in many ways.
This is probably key. For example, the term grapple doesn't really have to mean bear-hugging; you could argue that a grandmother who's dragging an unruly child away by the ear has effectively "grappled" him. Or shoving a wyvern mid-flight could be described as slamming your shield into the back of it's head to stun it just enough to fall from the sky. That kind of thing. It all seems so ridiculous at first, but the more I think about it, the more I think the crazy situations *can* actually be described well enough.
