If you're just casually venting about something on social media or to a friend in a text and don't necessarily care about holding some type of reputation, you're probably fine to use FUBAR.
Haddii aad si ula kac ah u daba-galayso wax ku saabsan warbaahinta bulshada ama saxiibka qoraalka ah oo aadan hubin inaad haysato nooc ka mid ah sumcadda, waxaa laga yaabaa inaad fiican tahay inaad isticmaasho FUBAR.
