It's important to note that:
* It's considered extremely rude and offensive. Using it in polite conversation would be inappropriate.
* It's more common in slang and informal speech. You'd be unlikely to hear it in formal settings.
If you're looking for a more polite way to say "disgusting," you could use words like:
* Dégoûtant (disgusting)
* Repoussant (repulsive)
* Révoltant (revolting)
* Abominable (abominable)
However, these words are still quite strong and should be used with caution.
