DU
DU(Drunks united) was started on October 15, 2006 by Thomas G from Smithtown High School. Immediately members flocked to DU marking the start of DU as we know it today. Later, three unusually slutty women(ranging from 130-450 lbs), joined followed by a junior at the time. Two months later these ladies were dropped from the group. DU has a total penis length of 250 feet, and is ethnically 83% white and 17% nazi. A negligible percent are asian.
"Wow that one kid in DU is fucking retarded."
