Someone who's brown (such as Indian, Sri Lankan.. mostly Sri Lankan) who posts pictures on Facebook, taken only among white-guys. None of their albums contain any pictures taken with fellow country-men. Also, they go to their workplace during holidays, and works extra shifts for free. Engages in "fucking the dog" most of the time, and seen with an iPhone in hand.

Dilan: Hey, did you see my facebook? Kumar: Hold on, lemme check.... Not again you tool, when are you gonna get over this white-guy obsession??

Originally meaning teacher's pet/suckup/brown-noser, this word has come to have a variety of other meanings now as well. The word tool in its latest and most common meaning originated from the USMA and USMA Prep School at West Point, New York (USMA=United States Military Academy)during the mid-late 1980s. One James Maynard Keenan attended West Point but dropped out eventually. He then created the popular band known as tool. An intersting factoid is that although keenan is now bald, in his school pictures from west point, he has what most call a "full head of hair." In some cases the word tool is used to mean dick.

Brian is a tool. That band tool is good.
