I'm gonna shuffle his deck clean

I heard a song recently that said "I'm gonna shuffle his deck clean." Any idea what this means?

I don't know what this particular author means, but if the deck is stacked you can clean the stacking out by repeated shuffling. BUt if we're trying to clean up an individual, perhaps persuade him to stop lying, I'm not sure how he can be shuffled.

I think it means shuffling so much that any "marks" on cards are removed by the constant friction. Thats how it sounds to me?
