a more brilliant way of saying that something is dumb-ish or someone is. dum-dum is "dumb" only that the b-sound is depleted and the new formed word is repeated twice to accent the state of being.
Omigosh! Here comes the dum-dum of the century!

An odd creature. In the form of a female, seems most reserved and reads constantly. But those arent your classic novels of fiction. Nope, this is porn dirtier than playboy magazine, the only diffrence is that its disguised with a story. This may explain why the Dum Dum aspires to become a pornstar.
Dude, Chealseas such a Dum Dum, i thought she didnt know what sex was, then I started reading her book, and it was like straight out of the Kama Sutra!

The only free public golf course in the United States. Located in Sharon, Pennslyvania, Buhl Farm Golf Course, otherwise known as "dum dums" by the locals, is a nine hole, par 34 course with slow, rolling greens and very narrow fiarways. The signature hole is the seventh hole, a 330 yard dogleg-right par 4 lined by trees on both sides with a small creek running right through the landing zone if you elect to hit driver. The course was donated by the great philanthropist Mr. Buhl, who wanted to build a course free to the public so kids could pick up the game of golf. There is a driving range on-site (which was donated by Arnold Palmer) and dum dums is also the home of The First Tee of Sharon.
