I made up that plural of phallus, and was waiting for one of our scholars to expose the error. When none did, I decided to do it myself. I get a chuckle out of what I found:

Etymology: Latin, from Greek phallos penis, representation of the penis;
probably akin to Latin flare to blow -- more at BLOW



Gee, Dr. Bill... all I asked for was some serious help in finding the background/origin of the word williwaw (tsuwm, NicolasW, are you out there?), and somehow we wind up with you discovering the etymolgy for b*** j**! How on Earth did we get from point A to point B (or point BJ), Good Doctor?
