v.; to burn, scar, blacken and otherwise damage some part of the body, particularly a hand.
From the name Dumbledore, character in the series of Harry Potter books, whose hand is injured and is scarred permanently.
You don't put your hand into acid unless you want it dumbledored.
Reference to "girl poo". There is usually no stink accompanied with this poo, unlike those produced by their male counterparts. The dumplette is generally small in size and requires minimal use of toilet paper.
Dumplette's are great in public restrooms because they're so discreet. One can walk out of the bathroom stall after the dumplette is made and not receive looks of disgust from others.
The dumplette could quite possibly be the commencement of the popular male notion that "women do not poop". Just because it is unseen, unheard, and unsmelled does not mean it does not exsist.
Jenny: "Wow, Sandra...that was a quick bathroom break you just took. You must have just had to go number 1, huh?"
Dumplesburg can be substituted for the name of any small, backwards town which is populated primarily by rednecks who adore Sarah Palin and Walmart, hate 'the gay', love Jesus (when convenient), and don't believe that ethics codes and tax laws should apply to them. The primary industry in Dumplesburg is adult gift shops and gentlemen's clubs.
