This Song A Longtime Concert Staple For AC/DC Is Essentially One Long Double Entendre-Laden Dirty Joke. On The Surface The Lyrics Seem To Chronicle The Narrator's Card Game With A Female Card Shark Who Ends Up Beating Him With The Card Mentioned In The Title. Of Course Lyrics Like "my Ace Was High" And "how Was I To Know She'd Been Dealt With Before" Give The Song A Different Thematic Shading That Transforms It Into A Bawdy Joke About Catching A Venereal Disease. If One Listens To The Live Version Of This Song If You Want Blood Bon Scotts Sings It With Its Real And Uncensored Lyrics .
