Rap group created by 50 Cent, current members are 50 himself, Tony Yayo and Lloyd Banks. They ran the rap game from 2002-2006. Group and label seems to be picking up steam and moving back into a powerful position in late 2011 and will take the rap game back over.

n. Musical group: A rap group hailing from Queens, New York composed of founding members 50 Cent, Lloyd Banks, Tony Yayo, and mixtape DJ DJ Whoo Kid. While Tony Yayo was in prison, Young Buck, formerly of the UTP clique ran by Juvenile and Cash Money Records was picked as a replacement. 50 Cent enjoyed underground success with the release of such albums as Power of the Dollar, launching wild disses at fellow rappers including Ja Rule (on I Smell Pussy and Back Down) and launching his all-dissing single, How To Rob, featuring The Madd Rapper , and G-Unit released one of their first mixtape compilations through Whoo Kid and DJ Clue entitled "50 Cent Is The Future/G-Unit is the future", featuring bangers like Banks Workout and a sample of Hit The Road. Their trademark cry of G-g-g-g-G-unit became a universal form of slang throughout their years and was adopted by everyone from hardcore street criminals to suburban white kids driving their mothers Lexus.

After the release of their first official album, Young Buck was added to the roster full time, and all of the members released solo albums in the following years (Lloyd Banks' Hunger For More, Young Buck's Straight Outta Cashville, and Tony Yayo's Thoughts of a predicate felon).

Game, or The Game, aka Jayceon Taylor, was added to the Aftermath/G-Unit/Shady Records label ran by Dr.Dre during the mixtape run of mid 2004 to early 2005, in which a dispute was launched with 50 Cent and Game involving credit for album writing over his multi-platinum smash The Documentary and the song How We Do. A confrontation outside New York radio station Hot 97 resulted in a shooting, which escalated the beef between 50 and Game, putting an end to the previous Murder Inc beef between 50 Cent and Ja Rule/Irv Gotti. In the interview, 50 claims that he was solely responsible for the writing credits and the success of The Documentary, which aggravated Game and caused him to form his own label, Black Wall Street, and to write songs such as 300 Bars and the album/mixtape/DVD Stop Snitchin' Stop Lyin'. As of date, 50 Cent has signed 5 new artists/groups to his G-Unit imprint, including Mobb Deep, Ma$e, Olivia, M.O.P., and Spider Loc. However, no members of G-Unit appear in 50's movie, Get Rich Or Die Tryin'.

The release date for the next G-Unit album has not been set as of date.
1. General use: Hey man, have you heard the new G-Unit?

2. Battle cry: G-g-g-g-g-G-Unit!!

3. Modified usage: G-Unot, created by Game: G-g-g-g-g-G-UNOT!
