DU
Commonly-used, abbreviated form of Delta Upsilon, the first non-secret fraternity, currently the world's only international non-secret, non-hazing fraternity. North America's fifth oldest fraternity, it was founded at Williams College, Mass in 1834.

It is also currently Canada's largest fraternity with 5 chapters. Commited to Building Better Men, Delta Upsilon's non-secrecy allows it to be held accountable to its four founding principles, the development of character, the promotion of friendship, the diffusion of liberal culture, and the advancement of justice.

I rushed DU, because I don't see the point of keeping a fraternity's values and rituals a secret.

DU
1) Depleted Uranium, a substance with incredible military value, and some minor(and horribly blown out of proportion) health risks attached to its use.

2) The Democratic Underground, the biggest bunch of raving lunatics the world has seen in my lifetime. Noted for absurd conspiracy theories, instant banning of any disagreeing viewpoints, and general stupidity.
1) Anyone who says that DU is a radiation risk is an idiot(toxological risk maybe, but not radiological)

2) Don't judge the left by the DU, even a righty like me doesn't hate them that much.
