You can tell where my mind is. When I read "intrusive double D's" I immediately thought of Morganna Roberts. Nicknamed "The Kissing Bandit," she was famous in the 1970s-80s-90s for running out on the field during baseball games and kissing various players. Her measurements were 60-23-39.
Of the four phrases that included an additional double-D, PRINCEOFWADDLES (for "Duck royalty?") was cute but STOCKPIDDLER (for "Trader who doesn't take the market seriously?") was just plain dumb. But I give Mark McClain credit for managing to include the Army post FTDIXNJ. I know that looks like a line from an eye chart but it's short for FORT DIX, NEW JERSEY.
