The song is about two people that are in unstable marriages, each a “house of cards”. A man is trying to convince a woman that they should abandon their marriages and become lovers since their marriages will eventually “fall off the table and gets swept under.” He predicts that someday something, “voltage spikes”, will cause her house of cards to collapse, and she will find herself in a loveless marriage. "Throw your keys in the bowl, kiss your husband goodnight" refers to key parties - swinger parties where all the couples throw their car keys into a bowl to swap mates. He ends the song by repeating the word “denial” with the chorus singing “your ears should be burning”- an idiom meaning that someone is talking about you when you are not present. People talk about her being in denial of the reality that her marriage is failing.
