Boston hardcore crew originating in circa 1991 out of the ashes of the dying Boston hardcore scene and the fall of earlier crews like the S.T.A.F.F Skins and The Scooby-Doo Posse. Chapters in Portland, ME and then Upstate NY were added in the mid and then later 1990s. Currently, in 2005, FSU has grown to absorb other crews nationwide, including Tek-9, Doom Family, OBHC, and Most hated Skins, amongst others, and has set chapters in Philly, NJ, Seattle, Chicago, Nor Cal, and LA. FSU has strong ties to the Outlaw Motorcycle Club due to Boston members moving into the world of 1%ers. FSU is on par with the other major hardcore crews DMS and CTYC but shows a more dominant presense nationwide and has a reputation for action and not hype. Lesser hardcore crews such a Courage Crew, etc. are not of the same caliber in reputation or intent.

Friends Stand United: A group, although some call them a 'gang', of friends that will always back each other up, especially in a fight. Most FSU members share interests in hardcore/metal music, are straight edge, and love to fight. FSU is currently the most popular and strongest hard-core/metal groups in America.

Originally started by Elgin James and friends in Boston, MA; FSU (sometimes known as Friends Stand United, but began as Fuck Shit Up) in violent response to the number of Neo-Nazi skinhead hate groups on the rise across the country. Outnumbered by Nazi skinheads, and other street gangs FSU compensated with viciousness and mob fights which eliminated the skinhead problem. However, this violence has gotten them banned from many venues for fear of fighting.

To date there are FSU chapters in Boston, New York, Philadelphia, New Jersey, Chicago, Seattle, and Los Angeles.

Common mottos for the group are:

"Where friends don't let friends stand alone"
Hey man don't start shit with those FSU guys becuase they will not back down.
