A slightly playful and informal response to statements your friends might make to politely communicate the scarceness of shit given. It is often a more appropriate response to minor things that does not merit a sincere “nice!”
Example 1:
Your frd: “I just went to see avengers, it’s the best movie everrr”
You: “nice!”
This does not sound sincere. And your friend will likely block you and never talk to you again which might be a good thing in this instance.
Example 2:
Your frd: “I just went to see avengers, it’s the best movie everrr”
You: “noice!”
We can immediate feel the difference here in tone, in this case if you do not probe any further, your friend will likely understand that you do not give a shit and will likely leave you on read but will not block you which in general is a good thing as you can always initiate the blocking.
