{}

If you asked for your opinion on a matter but you have nothing constructive (or non-controversial) to say, send {}. The empty space between the curly brackets represents the "no comment." There are several slang variations to communicate that you have nothing to say, with two of the most notable ones being "NC" and "N/C." The curly brackets are a bit more creative than the standard acronyms. However, it may be more confusing for the recipient unfamiliar with {}. An example of when you might use {} is when you are asked for your opinion during a heated debate on Twitter and you don't have the energy to join. Or, you might be asked who you think the best Kardashian is and you just don't care.
