There's a couple ideas floating around the team...
One: A big long acronym that no one knows what it means...
IDKWTM (I dont know what this means) for example
Two: BJ Bumpers... I like this one, it's cute

Three: Various screen names, Daru, Vadus, etc...
Others...
PSP... after the PSP comercial... because it's like cheese you can take with you... At least it is now, after "weight reduction" day... we had to cut 25 pounds ;-;
