A hot button is a topic in someone's mind that when discussed makes them offended or very passionate about the issue. These things can be about people, religion, politics, possessions or passions.
When I talked to my girlfriend about her dead father, she got really pissed off and slapped me in the face. I guess that was a hot button issue for her.
