The phrase “I’ll bite” is used when you’re given an opening to respond to a question or statement, and you suspect that there might be some negative consequence; it’s a trick question, or someone’s trying to lure you into a prank or trap . By saying “Ok, I’ll bite,” you’re acknowledging the risk of sounding wrong or falling victim to the other person’s joke, and it implies that you’re willing to take that risk and play along anyway.
The meaning is that someone is baiting you, and you, being the “fish“ in this scenario, are willing to “bite” the bait and potentially get caught.

A: I’m sure this is a trick, but ok – I’ll bite. What are the five words?
