QBD is the quote database at www.bash.org. It consists of thousands of very geeky/nerdy quotes that people have submitted from IRC conversations. Some are funny, some are disguisting, and some are just totally gay.
An Example quote from QDB:
<ORi0N> what good are you with a high IQ if you, for exapmle, can't even make a sadwich or something?
<BaToR> ask that to stehpen hawking :p
Abbreviation for Queen Douche Bag.
A far superior alternate as opposed to simply calling someone a db
