People typically say something or somebody is "f***ed up" when they perceive it/them as having a bad or undesirable quality, as if damaged in some way.
Dadku sida caadiga ah waxay yiraahdaan wax ama qofku "f *** ed" marka ay u arkaan in ay yihiin tayada xun ama aan loo baahnayn, sida haddii ay waxyeelo u gaarto.
