nono
Something off-limits
A nono is something forbidden, inadvisable, or socially unacceptable—a violation of rules or norms.
Usually spelled as two words or hyphenated: Wearing white after Labor Day used to be a no-no.
The reduplicated form suggests childish speech, giving it a lighthearted tone even when the prohibition is serious: Texting while driving is a big no-no.
