Widely used in Russia word, that means "a total kaput ".
Very useful when you wanna be expressive and avoid censored words at the same time.
Coming probably from the french word "gabelle", unpopular Indirect tax on salt (under the Ancient Regime, in France).
And the term "gabelle" is derived from the Italian "gabella" (a duty), itself originating from the Arabic word قَبَلَ (qabala, "he received").
So, having the duty = total end of everything.
*gave a first blood in LoL* *team yelling at you*
- It's gabella.
