I don't want to nit-pick, but what's the signal for "Over the Back" as you mentioned.

She said "over-AND-back" not "over THE back."

In my experience, if you call the violation while the player is still OOB and use your voice: tweet - "15 is OOB .. white" - point; then the confusion will be minimized.

The whistle will cause the coach to look at you and s/he'll see the player involved.
