a-okay
All systems go
A-okay means perfectly fine, completely satisfactory—often with a note of cheerful reassurance.
The phrase intensifies plain okay, originally from NASA mission control jargon in the early space program: Mission control confirmed the systems were a-okay.
It can sound dated or deliberately folksy: Everything's a-okay here, don't worry about us.
