Slang: 1)Of or relating to leaving.2) Exiting, may be applied to a physical location or
death (i.e. leaving
earth/life) First emerged in the golden era of hip-hop in 1991 on Ice Cube's 2nd solo album "Death Certificate" in the track entitled "Alive on Arrival". After suffering a gunshot wound and being harassed by
police in the hospital the lyrics are as follows; "...too many black bodies the hospital housin' so at 10pm I was outie 5000"
"I'm
late picking up my girlfriend, Im outie 5000"...
Please note that a shortened version of this slang term exists as well. You
may take the "outie" out of the saying and just say "Im 5000". For example; "Call me later, I'm 5000".
