Short for fucked. You know how there's that phrase, mofo, where the mo is "
mother" and the fo is "fucker"? It's sort of like that.
When using this to shorten the phrase "Fucked up", it is not necessary to say "fo'd up". "fo'd"
will work.
Man, that Datura shit is fo'd. I went
crazy for a day, and I still can't read anything.

Man2: Dammit! He fo'd my ultimate
gaming machine! Even my boomslang
mouse is fo'd!
Man1: L33t.
