C’est naze/c’est nul / c’est pourri When to use?
I was wondering what the different correct uses are for these three phrases as they are fairly similar in English.

C’est naze
c’est nul
c’est pourri

Answer

Well, all those are VERY familiar expressions in French.
The one I would use, if I had to choose between those 3, is "c'est nul" because it's a bit less unpolite.
Like you could say: "Oh, la piscine est fermée aujourd'hui, c'est nul! Je comptais y aller."
I would not use the 2 others. Only children would say them.

Answer

Also,
Informal language: naze et pourri(e) -> pourri (masculin) pourriE (féminin)
Colloquial language: nul (masculin) nulle (féminin)
