one-offs
Never again events
One-offs are things made, done, or happening only once—not part of a series or regular production.
A manufacturer might produce a one-off prototype.
A band might play a one-off reunion show.
The term often emphasizes uniqueness or the absence of commitment to repetition: It was just a one-off; we're not making it a regular thing.
As an adjective: a one-off payment, a one-off event.
