What is the code for pinching nose

The code for pinching the nose is not a standard term or command in English or in any other widely-used language that I am aware of. Pinching the nose may be a descriptive phrase for a particular action or gesture, but it lacks a specific code or terminology in the realm of English language usage. If you're referring to a particular symbol or gesture that represents pinching the nose, it may be an individual or cultural gesture that does not have a universal code or standard. Please provide more context or clarify your question if you need more assistance.
