When something really lame occurs, one may exclaim "D.U."

Someone who is possessed by clout chasing. The original human is now gone and a demonic entity that feeds on clout is all that is left. An empty shell with no control of their actions, forced to blindly react to situations they think will bring them attention.

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.

A contracted form of the word dude. In the same way foo is the shortened version of fool.

Do and you combined
