The act of baiting someone into (incorrectly) calling bullshit

A good term for this is double bluff. Collins defines it as:

a truthful action that is executed as if it were a bluff

If you have a good position and make it appear you do not (by faking a tell, loudly proclaiming your ace-high flush, etc) in order to goad them into calling your bluff, you are double bluffing.

This can also be applied the other way. If you have a weak hand, you could double bluff by actually signalling a weak hand in some way, making your opponent assume you're lying (because who signals a weak hand?).

Two options come to mind.

Sandbagging is more general and I've seen it used in a variety of ways (including metaphorical).

Slow playing I've generally heard more in reference to the actual poker strategy, but I have seen a few occasions where it was also used metaphorically.

Would bait, feint, or lure fit your definition? Maybe these are too broad, but I usually see baiting as a term used to lure someone into an argument.

You might use Muhammad Ali's rope-a-dope, about which Wikipedia says it is "used to describe strategies in which one party purposely puts itself in what appears to be a losing position, attempting thereby to become the eventual victor."
