A play on words?

My eldest son and I were playing a game of cards. The game where you have to grab up the jack when you see it being laid down. I guess I got a little too into the game because I saw the jack and I swiped at it fiercely. Unfortunately, I scratched my sons hand in the process. I said, "I'm so sorry, sweetheart!" And he replied, "Wow, Mama, you have a big snatch!!" I laughed hysterically for about five minutes.
