People use this expression about a hand where you think you might actually have the best hand, even though what you have is pretty weak. Betting isn't +EV because no one is going to call unless you're beat. It's better to try for a free showdown.

Like when you have mid pair and there's alot of draws out there, you will only get called (or worse) reraised by a better hand
